Security level
Needs improvement
Data confidenceHigh
Scope checked97.3%
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.
Address “Allowed browser content (CSP)” first, then review the remaining findings in order of impact. The scan found 16 items to review with 97.3% coverage. Some evidence remains incomplete, so the 69.7/100 score is provisional.
Across 5 checked network reputation sources, CyStack did not find vncare.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
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.

Evidence in this report
A valid SSL certificate alone does not prove that vncare.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.
vncare.vn presented a valid HTTPS certificate at assessment time, valid until September 26, 2026. This status can change when the certificate or server configuration is updated.
Review HTTPS and certificateNo record associated with an @vncare.vn email address was found in the currently available data. This does not rule out incidents that have not been observed.
Data 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.
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.

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 1 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 72 potentially applicable CVE candidate(s), including 31 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
CyStack confirmed at least 26 active DNS subdomains. 5 names may expose sensitive services; discovery was partial, so more may exist.
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
No explicit MX or Null MX record was found.
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.
Check result
No explicit MX or Null MX record was found.
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.
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
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 4 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 1 versioned product(s); 1 had exact CPE mappings and 1 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 certificate matches the requested 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.
Recorded data
Check result
The certificate chains to a trusted root.
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.
Recorded data
Check result
A TLS handshake succeeded on port 443.
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.
Recorded data
Check result
The target resolved to 2 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 management service was found on the scanned TCP port set.
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.
Recorded data
Check result
No public datastore service was found on the scanned TCP port set.
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
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
The certificate is valid from 2025-08-25T09:05:17Z to 2026-09-26T09:05:16Z.
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.
Recorded data
Check result
The certificate uses SHA256-RSA with a 2048-bit public key.
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.
Recorded data
Check result
Accepted versions: TLS 1.2.
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.
Recorded data
References
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
The server presented 3 certificate(s).
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.
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
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 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
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
Check result
This check does not apply to the target.
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.
Check result
This check does not apply to the target.
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.
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
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.
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
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 6 technologies on vncare.vn, including 1 with a version, and found 72 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 2 public IPs and 3 open ports for vncare.vn; the infrastructure appears to be operated by Vietnam Posts and Telecommunications Group. 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 26+ public subdomains of vncare.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.

A 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_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port.
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.
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
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.
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.
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.
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.
NvdThe Apache HTTP Server through 2.4.23 follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states "This mitigation has been assigned the identifier CVE-2016-5387"; in other words, this is not a CVE ID for a vulnerability.
NvdThe byterange filter in the Apache HTTP Server 1.3.x, 2.0.x through 2.0.64, and 2.2.x through 2.2.19 allows remote attackers to cause a denial of service (memory and CPU consumption) via a Range header that expresses multiple overlapping ranges, as exploited in the wild in August 2011, a different vulnerability than CVE-2007-0086.
NvdA carefully crafted If: request header can cause a memory read, or write of a single zero byte, in a pool (heap) memory location beyond the header value sent. This could cause the process to crash. This issue affects Apache HTTP Server 2.4.54 and earlier.
NvdApache HTTP Server, in all releases prior to 2.2.32 and 2.4.25, was liberal in the whitespace accepted from requests and sent in response lines and headers. Accepting these different behaviors represented a security concern when httpd participates in any chain of proxies or interacts with back-end application servers, either through mod_proxy or using conventional CGI mechanisms, and may result in request smuggling, response splitting and cache pollution.
NvdApache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c.
NvdA specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30 due to an out of bound read while preparing data to be cached in shared memory. It could be used as a Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.
NvdMalformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier.
NvdA carefully crafted request body can cause a read to a random memory area which could cause the process to crash. This issue affects Apache HTTP Server 2.4.52 and earlier.
NvdIn Apache HTTP Server 2.4.53 and earlier, a malicious request to a lua script that calls r:parsebody(0) may cause a denial of service due to no default limit on possible input size.
NvdApache HTTP Server 2.4.53 and earlier may return lengths to applications calling r:wsread() that point past the end of the storage allocated for the buffer.
NvdThe comparison found 72 potential matches for this product, but this report contains only a limited detail sample.
