Security level
Low
Data confidenceHigh
Scope checked95.5%
A higher score means more observable Internet-facing protections were recorded; it is not proof that the website is legitimate, entirely safe, or free of vulnerabilities.
Transport protection needs priority attention. Validate the certificate and TLS configuration before addressing lower-impact items. The provisional score is 43.3/100 with 95.5% coverage. It reflects only the parts of the attack surface with sufficient evidence.
Across 5 checked network reputation sources, CyStack did not find xdns.vn or related infrastructure on a warning list. This does not verify the organization, its business practices, or guarantee that the website is completely safe.
The three issues to address first because they have the greatest security impact.
Check result
This check found a security issue.
Why it matters
If either a password page or the address receiving its form uses HTTP, someone observing the network may read or change the submitted password.
What to do
Serve every page containing a password field over HTTPS and submit each password form directly to an HTTPS address.
Recorded data
Compare the security level of each area at a glance.
Evidence in this report
A valid SSL certificate alone does not prove that xdns.vn is safe or legitimate. For a fuller picture, this report also checks scam, phishing, and malware signals, exposed email records, IPs and open ports, subdomains, technologies, and CVEs that may apply to detected versions.
HTTPS on xdns.vn could not be reached during this assessment, so its SSL certificate and transport encryption could not be evaluated.
Review HTTPS and certificateNo record associated with an @xdns.vn email address was found in the currently available data. This does not rule out incidents that have not been observed.
Review exposed email recordsData sources and scope
This scan result is compiled from CyStack's cybersecurity monitoring systems, including CyStack VulnScan and CyStack Threat Intelligence, together with publicly available Internet data. The assessment only observes and analyzes information already available; it does not attempt unauthorized access, test passwords, send exploit code, or change or disrupt your systems.
CyStack VulnScan for enterprises
CyStack VulnScan helps security teams automatically find Internet assets, scan external and internal systems, validate vulnerabilities and track remediation across the organization.

Why it matters
HTTPS encrypts data between visitors and the website and helps prove they reached the intended service. Without it, network observers may read or alter traffic and browsers may show a security warning.
What to do
Provide the entire website over HTTPS using a certificate trusted by common browsers.

Check result
A confirmed public management service was found: 115.146.122.152:22 (ssh).
Why it matters
Remote administration services such as RDP, VNC, Docker, Kubernetes, and management consoles are high-value targets. Public exposure allows anyone on the Internet to attempt passwords or exploit an unpatched service.
What to do
Remove direct Internet access and require a VPN, a hardened access gateway, or trusted source networks; also use MFA where supported.

A confirmed public datastore service was found: 115.146.122.152:6379 (redis), 115.146.122.152:27017 (mongodb).
Why it matters
Databases and caches often contain sensitive information and are normally used only by internal applications. Direct Internet access makes password attacks and configuration mistakes much more likely to become a data breach.
What to do
Listen only on private interfaces, allow connections only from required application systems, and require strong authentication and encryption.
Recorded data
Check result
This check found a security issue.
Why it matters
HttpOnly prevents browser scripts from directly reading a cookie. It does not fix script injection, but it makes theft of session and authentication cookies more difficult.
What to do
Set HttpOnly on session and authentication cookies unless the application has a documented need to read them in browser code.
Recorded data
Check result
This check found a security issue.
Why it matters
The Secure attribute prevents a browser from sending a cookie over unencrypted HTTP. Without it, session or authentication data may be exposed to someone observing the network.
What to do
Set Secure on every session, authentication, and other sensitive cookie served by the HTTPS application.
Recorded data
Check result
This check found a security issue.
Why it matters
Content Security Policy (CSP) limits where scripts, styles, frames, and other browser content may come from. A strong policy reduces the impact if an attacker manages to inject content into a page.
What to do
Define only the sources the application needs, test the policy before activating it, and avoid broad wildcard (*) rules, unsafe-inline, and unsafe-eval where possible.
Recorded data
References
Check result
No DMARC policy was found by domain tree walk.
Why it matters
DMARC lets the domain owner tell receiving services what to do when the visible From address is not verified by SPF or DKIM. Without DMARC, attackers have more opportunity to impersonate the domain in phishing email.
What to do
Publish a DMARC record at _dmarc, begin by collecting reports, and confirm that legitimate senders pass before applying a blocking policy.
References
Check result
This check found a security issue.
Why it matters
Another website can place this page inside a hidden or misleading frame and trick a user into clicking an unintended action. Frame restrictions tell browsers which sites, if any, may embed the page.
What to do
Set frame-ancestors in CSP to the required trusted sites, and keep X-Frame-Options for older browsers when appropriate.
Recorded data
References
Check result
This check found a security issue.
Why it matters
Without the nosniff setting, a browser may guess a file's type and treat harmless-looking content as executable code. This can turn an incorrect Content-Type into a security issue.
What to do
Send X-Content-Type-Options: nosniff on every response and return an accurate Content-Type.
Recorded data
References
Check result
The HTTP root remains reachable without completing an HTTPS redirect.
Why it matters
Visitors may enter an address beginning with HTTP or follow an old link. Redirecting them immediately to HTTPS prevents the rest of the visit from continuing over an unencrypted connection.
What to do
Redirect every HTTP URL directly to its corresponding HTTPS URL without passing through another HTTP address.
Recorded data
Check result
No SPF record was found.
Why it matters
Sender Policy Framework (SPF) lists the systems allowed to send email for the domain. Without it, receiving services have less evidence to distinguish legitimate mail from spoofed mail.
What to do
Publish one SPF TXT record that includes every legitimate email service and no unauthorized sender.
References
Check result
This check found a security issue.
Why it matters
Permissions-Policy controls whether this page and embedded content may use features such as the camera, microphone, and location. Leaving unused features available creates unnecessary access paths.
What to do
Allow each sensitive browser feature only for the pages and trusted origins that require it, and disable the rest.
Recorded data
References
Check result
This check found a security issue.
Why it matters
When a visitor follows a link, the browser may send the previous page's URL to the destination. Paths and query values in that URL can reveal sensitive context to another website.
What to do
Use strict-origin-when-cross-origin or a stricter Referrer-Policy, and avoid placing secrets in URLs.
Recorded data
References
Check result
This check found a security issue.
Why it matters
Exact web server or framework versions help attackers quickly look for known weaknesses that may apply. Hiding a version is not a substitute for patching, but unnecessary disclosure gives away useful targeting information.
What to do
Remove unnecessary version details from Server, X-Powered-By, error pages, and application metadata, and keep the software patched.
Recorded data
Check result
Found 4 known-exploited candidate(s), but the external product fingerprint requires verification.
Why it matters
A possible CVE match also appears in the CISA Known Exploited Vulnerabilities (KEV) catalog, which means attackers have used that vulnerability in real incidents. The match is urgent to investigate, but the installed software still needs to be confirmed as affected.
What to do
Verify the installed product immediately and follow the CISA and vendor instructions for mitigation, patching, or upgrading if it is affected.
Recorded data
Check result
Found 155 potentially applicable CVE candidate(s), including 86 high or critical candidate(s).
Why it matters
The detected product and version were compared with vulnerability records from the National Vulnerability Database (NVD). A match is a lead, not confirmation: the installed software may include vendor fixes or may differ from the version visible on the Internet.
What to do
Confirm the exact installed package and read the vendor advisory. If that installation is affected, apply the vendor patch or upgrade to a fixed version.
Recorded data
Check result
Found 0 applicable CAA record(s).
Why it matters
Certificate Authority Authorization (CAA) records state which certificate providers may issue certificates for the domain. This reduces the chance of an unintended provider issuing one.
What to do
Publish CAA records that allow only the certificate providers your organization actually uses.
References
Check result
No DNSSEC DS delegation was found.
Why it matters
DNSSEC adds digital signatures so resolvers can detect forged DNS answers. This quick check confirms the parent domain has a DS record, but it does not validate the complete signature chain.
What to do
Sign the DNS zone, publish the matching DS record through the registrar, and monitor the signature chain after key changes.
References
Check result
The scan did not collect enough evidence for a reliable conclusion.
Why it matters
An expired domain stops directing users to the organization's services and may eventually become available to someone else. A domain close to expiry leaves little time to recover from payment or account problems.
What to do
Renew well before the expiry date, enable automatic renewal, and protect the payment method and registrar account.
Check result
The scan did not collect enough evidence for a reliable conclusion.
Why it matters
Registrar or registry restrictions such as hold, redemption, or pending deletion can disable the domain. If they are not resolved, the organization may lose control of its website and email identity.
What to do
Resolve registration restrictions promptly, protect the registrar account with MFA, and keep ownership and contact information current.
Check result
CyStack confirmed at least 5 active DNS subdomains. Some discovery checks were incomplete, so this is a minimum rather than a final total.
Why it matters
Names containing admin, development, staging, VPN, database, or monitoring terms may point attackers toward valuable systems. A name alone does not prove exposure, but it identifies a surface that should be reviewed.
What to do
Remove obsolete DNS names and protect non-public systems with strong authentication, MFA, network allowlists, or a VPN.
Recorded data
Check result
5 providers were definitive and 1 were inconclusive.
Why it matters
This shows how many independent blacklist services returned a clear result. A service that was unavailable was not checked successfully and must not be treated as a clean result.
Recorded data
Check result
Public signals from the website and its open services revealed 7 technology item(s).
Why it matters
Response headers, page content, and other public clues suggest which technologies the service uses. These observations help explain the attack surface, but they can be incomplete or mistaken and do not by themselves confirm a vulnerability.
Recorded data
Check result
No WAF, CDN, or edge product matched the passive root-response signals; this does not prove that protection is absent.
Why it matters
Public response details suggest that a Web Application Firewall (WAF), CDN, or other edge service is present. This quick scan identified the provider but did not test whether attack blocking is configured or working correctly.
Recorded data
Check result
Observed 5 versioned product(s); 5 had exact CPE mappings and 5 completed lookup(s).
Why it matters
This shows how many detected products had reliable version information and an exact CPE identity, allowing them to be checked against CVE applicability data. A product that could not be checked must not be treated as free of known vulnerabilities.
Recorded data
Check result
The target resolved to 1 public IP address(es).
Why it matters
Public DNS connects the domain to its Internet addresses. Missing or incorrect records can make the service unreachable or send traffic to the wrong system.
What to do
Make sure the domain resolves only to its intended public IP addresses, and remove private, reserved, or outdated records.
Recorded data
Check result
No public file-sharing service was found on the scanned TCP port set.
Why it matters
Services such as SMB, NFS, and rsync can reveal or modify shared files and have a history of serious vulnerabilities. They rarely need to accept connections directly from the public Internet.
What to do
Limit file-sharing services to private networks or a tightly controlled VPN, and allow only the users and systems that require access.
Recorded data
Check result
No public legacy cleartext service was found on the scanned TCP port set.
Why it matters
Older services such as Telnet, FTP, and unencrypted mail or directory protocols can send passwords and data in readable form. Anyone able to observe the network path may capture them.
What to do
Disable the legacy service or replace it with an encrypted alternative such as SSH, SFTP, HTTPS, or the secure version of the mail protocol.
Recorded data
Check result
No issue was found by this check.
Why it matters
Cross-Origin Resource Sharing (CORS) decides which websites may read responses from this service in a visitor's browser. Rules that trust arbitrary origins, especially with login cookies, can expose private data to another website.
What to do
Allow only explicitly trusted websites, compare the Origin value with an exact approved list, and never allow login credentials with the wildcard origin (*).
Recorded data
Check result
No independent abuse-list consensus was found across 5 definitive providers.
Why it matters
Security and email providers maintain DNS-based blacklists of IP addresses associated with spam, malware, or compromised systems. Several current, independent listings are a strong reason to investigate, although a shared IP can sometimes affect unrelated customers.
What to do
Verify each listing against the affected IP, investigate mail and host activity, fix the underlying cause, and then follow the provider's removal process.
Recorded data
Check result
No issue was found by this check.
Why it matters
SameSite limits when a browser includes cookies in requests started by another website. This helps prevent another site from silently making an authenticated request on a user's behalf.
What to do
Use SameSite=Lax or Strict by default. Use SameSite=None only for a required cross-site flow and always combine it with Secure.
Recorded data
Check result
The root page did not match a common automatic directory-index pattern.
Why it matters
When a web server automatically lists a directory, visitors may discover files that were never linked publicly, including backups, logs, or deployment artifacts.
What to do
Disable automatic directory indexes unless public file browsing is an intentional feature, and remove sensitive files from web-accessible folders.
Recorded data
Check result
No matching credential exposure records were found in the currently indexed intelligence data. This does not prove that no exposure exists.
Why it matters
Infostealer intelligence may contain credentials associated with the domain, but it does not prove that an account is current, valid, or still exposed.
What to do
Review the masked evidence and observation time, validate affected accounts and devices, then reset active credentials and sessions, enforce MFA, and remove malware where confirmed.
Recorded data
Check result
Found 1 MX record(s); 0 target(s) were invalid.
Why it matters
MX records direct incoming email to the correct mail servers. Broken records can stop delivery, while a Null MX clearly tells senders that the domain does not receive email.
What to do
Correct unreachable or outdated MX hosts, or publish a Null MX if the domain is not intended to receive email.
Recorded data
Check result
No public unexpected service was found on the scanned TCP port set.
Why it matters
Every open service can be discovered and attacked and must be configured, monitored, and patched. Services without a clear public purpose add risk without providing business value.
What to do
Confirm the owner and purpose of every open port, then stop or firewall any service that is not intentionally public.
Recorded data
Check result
Found 1 MX record(s); 0 target(s) were invalid.
Why it matters
A domain should clearly state whether it receives email. Without valid MX records or a Null MX, senders may try an unintended server and delivery behavior becomes unpredictable.
What to do
Publish valid MX records for the intended mail servers, or a Null MX if the domain never accepts email.
Recorded data
Check result
Found 2 authoritative name server(s).
Why it matters
Authoritative name servers tell visitors where the domain is hosted. Depending on only one server creates a single point of failure for the website and email.
What to do
Use at least two authoritative name servers, preferably on independent and resilient infrastructure.
Recorded data
Check result
This check does not apply to the target.
Why it matters
The certificate must list the exact hostname visitors requested in its Subject Alternative Names (SAN). A mismatch produces browser warnings because the certificate may belong to a different service.
What to do
Issue and deploy a certificate whose SAN list includes every public hostname served by this website address.
Check result
This check does not apply to the target.
Why it matters
Browsers trust a website only when its certificate can be traced to a recognized certificate provider. An untrusted certificate causes warnings and prevents visitors from reliably confirming the website's identity.
What to do
Install a certificate from a provider trusted by common browsers and configure the server to send every required intermediate certificate.
Check result
This check does not apply to the target.
Why it matters
A certificate works only between its start and expiry dates. An expired, not-yet-valid, or soon-to-expire certificate can trigger browser warnings and interrupt access to the website or API.
What to do
Use automatic renewal, monitor renewal failures, and alert the responsible team well before expiry.
Check result
This check does not apply to the target.
Why it matters
The certificate's public key and signature algorithm protect it from forgery. Keys that are too short or signatures based on obsolete algorithms provide less protection against modern attacks.
What to do
Use RSA with at least 2048 bits or a modern elliptic-curve key, and use SHA-256 or a stronger signature algorithm.
Check result
This check does not apply to the target.
Why it matters
TLS 1.0 and TLS 1.1 use outdated security designs and are no longer accepted by modern standards. Leaving them enabled allows older, weaker connection methods.
What to do
Disable TLS 1.0 and TLS 1.1, support TLS 1.2 securely, and enable TLS 1.3 where possible.
References
Check result
This check does not apply to the target.
Why it matters
A policy of quarantine or reject tells receiving services to move suspicious mail to spam or refuse it. A monitoring-only policy (p=none) records the problem but does not ask receivers to stop spoofed mail.
What to do
After every legitimate sender passes DMARC, move gradually to quarantine and then reject, covering 100% of messages.
References
Check result
This check does not apply to the target.
Why it matters
Receiving services may ignore a DMARC record that contains duplicate fields, invalid values, or is published at the wrong DNS name. An ignored record provides no reliable protection from domain impersonation.
What to do
Publish one valid DMARC record at _dmarc and correct duplicate fields, unsupported values, and invalid report addresses.
References
Check result
This check does not apply to the target.
Why it matters
An HTTPS page can still load scripts, frames, styles, or forms over unencrypted HTTP. An attacker on the network may alter that content and compromise the otherwise secure page.
What to do
Load every script, frame, stylesheet, and form destination over HTTPS, and remove or replace resources that do not support it.
Check result
This check does not apply to the target.
Why it matters
The server must provide the intermediate certificates that connect its website certificate to a trusted provider. If any are missing, some browsers, mobile devices, or API clients may reject the connection.
What to do
Configure the server to send the website certificate followed by every required intermediate certificate, but not the root certificate.
Check result
This check does not apply to the target.
Why it matters
HTTP Strict Transport Security (HSTS) tells a browser to use HTTPS automatically on future visits. This reduces the chance that a visitor is downgraded to an unencrypted connection.
What to do
After confirming that every required page works over HTTPS, send the Strict-Transport-Security header on all HTTPS responses.
Check result
This check does not apply to the target.
Why it matters
The final SPF rule tells receiving services how confidently they should reject unlisted senders. A permissive result allows more spoofed mail to appear legitimate than a hard fail (-all).
What to do
Confirm that every legitimate sender is included, then end the SPF record with -all.
References
Check result
This check does not apply to the target.
Why it matters
More than one SPF record, invalid terms, or too many DNS lookups can make SPF return a permanent error. Receiving services may then be unable to verify authorized senders.
What to do
Keep one valid SPF record, remove invalid terms, and remain within the SPF limit of ten DNS-based lookups.
References
Check result
This check does not apply to the target.
Why it matters
The max-age value controls how long browsers remember to use HTTPS. A very short period provides limited protection, while includeSubDomains also covers every subdomain and can break one that does not support HTTPS.
What to do
Use a long max-age, and add includeSubDomains only after confirming that every active subdomain works correctly over HTTPS.
Check result
This check does not apply to the target.
Why it matters
DMARC aggregate reports show which systems send email using the domain and which messages fail verification. They help find both impersonation attempts and legitimate services that need correction.
What to do
Add an aggregate report address (rua) that is protected and monitored, or use a trusted DMARC reporting service.

Data provided by CyStack Threat Intelligence.
This is a quick, point-in-time check from outside the organization. It can surface visible risks, but it does not replace penetration testing or an authenticated assessment.
The assessment identified 9 technologies on xdns.vn, including 5 with a version, and found 155 CVEs that may apply. Each result needs version and configuration validation before it is treated as a confirmed vulnerability.
Review technologies and CVEsThe assessment observed 1 public IPs and 4 open ports for xdns.vn; the infrastructure appears to be operated by CMC Telecom Infrastructure Company. An open port is not automatically a vulnerability, but every public service should be updated and appropriately restricted.
Review IPs and open portsThe assessment observed 5+ public subdomains of xdns.vn. This inventory can reveal additional entry points such as APIs, administration systems, or test environments, but it does not imply that every subdomain is risky.

Openssh7.429 potential CVEsCVSS 9.8Potential CVEs for this product
The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009.
Nvdssh in OpenSSH before 10.4 can have a use-after-free when a server changes its host key during a key re-exchange. (This outcome occurs only on the client side.)
NvdIn OpenSSH before 10.3, a file downloaded by scp may be installed setuid or setgid, an outcome contrary to some users' expectations, if the download is performed as root with -O (legacy scp protocol) and without -p (preserve mode).
NvdOpenSSH before 10.3 mishandles the authorized_keys principals option in uncommon scenarios involving a principals list in conjunction with a Certificate Authority that makes certain use of comma characters.
NvdIn sshd in OpenSSH before 10.4, DisableForwarding=yes was supposed to take precedence over PermitTunnel=yes, but did not.
Nvdsshd in OpenSSH before 10.4 allows remote attackers to cause a denial of service (resource consumption from excessive authentication attempts) because MaxAuthTries was mishandled for GSSAPIAuthentication.
Nvdscp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows."
Nvdsshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group memberships of the sshd process, if the configuration specifies running the command as a different user.
NvdAn issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c.
NvdIn OpenSSH 7.9, due to accepting and displaying arbitrary stderr output from the server, a malicious server (or Man-in-The-Middle attacker) can manipulate the client output, for example to use ANSI control codes to hide additional files being transferred.
NvdA vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high.
NvdIn ssh in OpenSSH before 9.6, OS command injection might occur if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. For example, an untrusted Git repository can have a submodule with shell metacharacters in a user name or host name.
NvdOpenSSH before 10.3 can use unintended ECDSA algorithms. Listing of any ECDSA algorithm in PubkeyAcceptedAlgorithms or HostbasedAcceptedAlgorithms is misinterpreted to mean all ECDSA algorithms.
Nvdsshd in OpenSSH before 10.4 has an undocumented security-relevant behavior: GSSAPIStrictAcceptorCheck has no value if the server is in Windows Active Directory.
Nvdsshd in OpenSSH before 10.4 does not always honor the minimum authentication delay.
NvdAn issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file).
NvdThe client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected.
NvdThe SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms. This also affects Maverick Synergy Java SSH API before 3.1.0-SNAPSHOT, Dropbear through 2022.83, Ssh before 5.1.1 in Erlang/OTP, PuTTY before 0.80, AsyncSSH before 2.14.2, golang.org/x/crypto before 0.17.0, libssh before 0.10.6, libssh2 through 1.11.0, Thorn Tech SFTP Gateway before 3.4.6, Tera Term before 5.1, Paramiko before 3.4.0, jsch before 0.2.15, SFTPGo before 2.5.6, Netgate pfSense Plus through 23.09.1, Netgate pfSense CE through 2.7.2, HPN-SSH through 18.2.0, ProFTPD before 1.3.8b (and before 1.3.9rc2), ORYX CycloneSSH before 2.3.4, NetSarang XShell 7 before Build 0144, CrushFTP before 10.6.0, ConnectBot SSH library before 2.2.22, Apache MINA sshd through 2.11.0, sshj through 0.37.0, TinySSH through 20230101, trilead-ssh2 6401, LANCOM LCOS and LANconfig, FileZilla before 3.66.4, Nova before 11.8, PKIX-SSH before 14.4, SecureCRT before 9.4.3, Transmit5 before 5.10.4, Win32-OpenSSH before 9.5.0.0p1-Beta, WinSCP before 6.2.2, Bitvise SSH Server before 9.32, Bitvise SSH Client before 9.33, KiTTY through 0.76.1.13, the net-ssh gem 7.2.0 for Ruby, the mscdex ssh2 module before 1.15.0 for Node.js, the thrussh library before 0.35.1 for Rust, and the Russh crate before 0.40.2 for Rust.
sftp in OpenSSH before 10.4 does not properly constrain the location of downloaded files when "sftp server:/path ." is used with an attacker-controlled server.
Nvdscp in OpenSSH before 10.4 may place a file in the parent directory of an intended directory when the copy occurs between two remote destinations.
Nvdinternal-sftp in sshd in OpenSSH before 10.4 recognizes only the first 9 command-line arguments, which can be important if a later command-line argument would have helped to ensure the intended security properties of an SFTP connection.
NvdOpenSSH through 8.7 allows remote attackers, who have a suspicion that a certain combination of username and public key is known to an SSH server, to test whether this suspicion is correct. This occurs because a challenge is sent only when that combination could be valid for a login session. NOTE: the vendor does not recognize user enumeration as a vulnerability for this product
NvdOpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c.
NvdRemotely observable behaviour in auth-gss2.c in OpenSSH through 7.8 could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. NOTE: the discoverer states 'We understand that the OpenSSH developers do not want to treat such a username enumeration (or "oracle") as a vulnerability.'
NvdIn OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side.

Mismatched length fields in Zlib compressed protocol headers may allow a read of uninitialized heap memory by an unauthenticated client. This issue affects all MongoDB Server v7.0 prior to 7.0.28 versions, MongoDB Server v8.0 versions prior to 8.0.17, MongoDB Server v8.2 versions prior to 8.2.3, MongoDB Server v6.0 versions prior to 6.0.27, MongoDB Server v5.0 versions prior to 5.0.32, MongoDB Server v4.4 versions prior to 4.4.30, MongoDB Server v4.2 versions greater than or equal to 4.2.0, MongoDB Server v4.0 versions greater than or equal to 4.0.0, and MongoDB Server v3.6 versions greater than or equal to 3.6.0.
NvdRedisVersion not visibleImproper escaping of output in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to map URLs to filesystem locations that are permitted to be served by the server but are not intentionally/directly reachable by any URL, resulting in code execution or source code disclosure. Substitutions in server context that use a backreferences or variables as the first segment of the substitution are affected. Some unsafe RewiteRules will be broken by this change and the rewrite flag "UnsafePrefixStat" can be used to opt back in once ensuring the substitution is appropriately constrained.
NvdA crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier.
NvdIn Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed.
NvdIn Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_mime can read one byte past the end of a buffer when sending a malicious Content-Type response header.
NvdIn Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection.
NvdIn Apache HTTP Server versions 2.4.0 to 2.4.46 a specially crafted SessionHeader sent by an origin server could cause a heap overflow
Nvdap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache HTTP Server 2.4.48 and earlier.
NvdA carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier.
NvdApache HTTP Server 2.4.52 and earlier fails to close inbound connection when errors are encountered discarding the request body, exposing the server to HTTP Request Smuggling
NvdOut-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and prior versions.
NvdApache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. This may be used to bypass IP based authentication on the origin server/application.
NvdSome mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a HTTP Request Smuggling attack. Configurations are affected when mod_proxy is enabled along with some form of RewriteRule or ProxyPassMatch in which a non-specific pattern matches some portion of the user-supplied request-target (URL) data and is then re-inserted into the proxied request-target using variable substitution. For example, something like: RewriteEngine on RewriteRule "^/here/(.*)" "http://example.com:8080/elsewhere?$1"; [P] ProxyPassReverse /here/ http://example.com:8080/ Request splitting/smuggling could result in bypass of access controls in the proxy server, proxying unintended URLs to existing origin servers, and cache poisoning. Users are recommended to update to at least version 2.4.56 of Apache HTTP Server.
NvdSubstitution encoding issue in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows attacker to execute scripts in directories permitted by the configuration but not directly reachable by any URL or source disclosure of scripts meant to only to be executed as CGI. Users are recommended to upgrade to version 2.4.60, which fixes this issue. Some RewriteRules that capture and substitute unsafely will now fail unless rewrite flag "UnsafeAllow3F" is specified.
NvdVulnerability in core of Apache HTTP Server 2.4.59 and earlier are vulnerably to information disclosure, SSRF or local script execution via backend applications whose response headers are malicious or exploitable. Users are recommended to upgrade to version 2.4.60, which fixes this issue.
NvdHeap-based Buffer Overflow vulnerability in mod_proxy_ajp of Apache HTTP Server. If mod_proxy_ajp connects to a malicious AJP server this AJP server can send a malicious AJP message back to mod_proxy_ajp and cause it to write 4 attacker controlled bytes after the end of a heap based buffer. This issue affects Apache HTTP Server: through 2.4.66. Users are recommended to upgrade to version 2.4.67, which fixes the issue.
NvdUse After Free vulnerability in Apache HTTP Server with mod_ldap in per-directory configuration This issue affects Apache HTTP Server: from 2.4.0 through 2.4.67. Users are recommended to upgrade to version 2.4.68, which fixes the issue.
NvdBuffer Underwrite vulnerability in Apache HTTP Server on crafted regular expressions in the configuration. This issue affects Apache HTTP Server: from 2.4.0 through 2.4.67. Users are recommended to upgrade to version 2.4.68, which fixes the issue.
NvdIn Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service.
NvdIf LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server 2.4.52 and earlier.
NvdApache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may hypothetically be affected.
NvdA path handling issue in mod_dav_fs in Apache 2.4.67 and earlier allows a WebDAV content author to directly manipulate trusted DAV property databases, potentially causing child process crashes. Users are recommended to upgrade to version 2.4.68, which fixes this issue.
NvdInconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.54 and prior versions.
NvdAn escalation of privilege bug in various modules in Apache HTTP 2.4.66 and earlier allows local .htaccess authors to read files with the privileges of the httpd user. Users are recommended to upgrade to version 2.4.67, which fixes this issue.
NvdApache HTTP Server 2.4.65 and earlier with Server Side Includes (SSI) enabled and mod_cgid (but not mod_cgi) passes the shell-escaped query string to #exec cmd="..." directives. This issue affects Apache HTTP Server before 2.4.66. Users are recommended to upgrade to version 2.4.66, which fixes the issue.
NvdIn Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. This could be exploited in environments where uploads of some files are are externally blocked, but only by matching the trailing portion of the filename.

The zend_string_extend function in Zend/zend_string.h in PHP through 7.1.5 does not prevent changes to string objects that result in a negative length, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact by leveraging a script's use of .= with a long string.
NvdAn issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an uninitialized read in exif_process_IFD_in_TIFF.
NvdA command inject vulnerability allows an attacker to perform command injection on Windows applications that indirectly depend on the CreateProcess function when the specific conditions are satisfied.
NvdThe GNU Multiple Precision Arithmetic Library (GMP) interfaces for PHP through 7.1.4 allow attackers to cause a denial of service (memory consumption and application crash) via operations on long strings. NOTE: the vendor disputes this, stating "There is no security issue here, because GMP safely aborts in case of an OOM condition. The only attack vector here is denial of service. However, if you allow attacker-controlled, unbounded allocations you have a DoS vector regardless of GMP's OOM behavior.
Nvdext/standard/var.c in PHP 5.x through 7.1.24 on Windows allows attackers to cause a denial of service (NULL pointer dereference and application crash) because com and com_safearray_proxy return NULL in com_properties_get in ext/com_dotnet/com_handlers.c, as demonstrated by a serialize call on COM("WScript.Shell").
Nvdext/standard/var_unserializer.c in PHP 5.x through 7.1.24 allows attackers to cause a denial of service (application crash) via an unserialize call for the com, dotnet, or variant class.
NvdAn issue was discovered in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. Due to the way rename() across filesystems is implemented, it is possible that file being renamed is briefly available with wrong permissions while the rename is ongoing, thus enabling unauthorized users to access the data.
NvdAn issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an uninitialized read in exif_process_IFD_in_MAKERNOTE because of mishandling the maker_note->offset relationship to value_len.
NvdAn issue was discovered in the EXIF component in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. There is an uninitialized read in exif_process_IFD_in_MAKERNOTE because of mishandling the data_len variable.
NvdPHP through 7.1.11 enables potential SSRF in applications that accept an fsockopen or pfsockopen hostname argument with an expectation that the port number is constrained. Because a :port syntax is recognized, fsockopen will use the port number that is specified in the hostname argument, instead of the port number in the second argument of the function.
NvdAn issue was discovered in PHP 7.3.x before 7.3.0alpha3, 7.2.x before 7.2.8, and before 7.1.20. The php-fpm master process restarts a child process in an endless loop when using program execution functions (e.g., passthru, exec, shell_exec, or system) with a non-blocking STDIN stream, causing this master process to consume 100% of the CPU, and consume disk space with a large volume of error logs, as demonstrated by an attack by a customer of a shared-hosting facility.
NvdIn PHP versions before 7.4.31, 8.0.24 and 8.1.11, the vulnerability enables network and same-site attackers to set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by PHP applications.
NvdIn PHP versions before 7.4.31, 8.0.24 and 8.1.11, the phar uncompressor code would recursively uncompress "quines" gzip files, resulting in an infinite loop.
