Dữ liệu MITRE CWE chính thức

Hiện thực hóa: When the product uses certificate pinning, the developer might not properly validate all relevant components of the certificate, such as verifying the hostname, before pinning the certificate. This can make it difficult or expensive to test after the pinning is complete.
Hiện thực hóa: REALIZATION: This weakness is caused during implementation of an architectural security tactic.

Tác động	Phạm vi	Diễn giải
Chiếm đặc quyền hoặc mạo danh	Kiểm soát truy cập	The data read from the system vouched for by the certificate may not be from the expected system.
Khác	Xác thực, Khác	Trust afforded to the system in question - based on the malicious certificate - may allow for spoofing or redirection attacks.
Chiếm đặc quyền hoặc mạo danh, Khác	Kiểm soát truy cập, Khác	If the certificate's host-specific data is not properly checked - such as the Common Name (CN) in the Subject or the Subject Alternative Name (SAN) extension of an X.509 certificate - it may be possible for a redirection or spoofing attack to allow a malicious host with a valid certificate to provide data, impersonating a trusted host.

Kiến trúc và thiết kếFully check the hostname of the certificate and provide the user with adequate information about the nature of the problem and how to proceed.
Hiện thực hóaIf certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.

Phương pháp	Cách làm	Hiệu quả
Phân tích tĩnh tự động	Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)	Cao
Phân tích động với diễn giải kết quả thủ công	Set up an untrusted endpoint (e.g. a server) with which the product will connect. Create a test certificate that uses an invalid hostname but is signed by a trusted CA and provide this certificate from the untrusted endpoint. If the product performs any operations instead of disconnecting and reporting an error, then this indicates that the hostname is not being checked and the test certificate has been accepted.	—
Hộp đen	When Certificate Pinning is being used in a mobile application, consider using a tool such as Spinner [REF-955]. This methodology might be extensible to other technologies.	—
