CWE-299 证书撤销验证不恰当
Improper Check for Certificate Revocation
结构: Simple
Abstraction: Base
状态: Draft
被利用可能性: Medium
基本描述
The software does not check or incorrectly checks the revocation status of a certificate, which may cause it to use a certificate that has been compromised.
扩展描述
An improper check for certificate revocation is a far more serious flaw than related certificate failures. This is because the use of any revoked certificate is almost certainly malicious. The most common reason for certificate revocation is compromise of the system in question, with the result that no legitimate servers will be using a revoked certificate, unless they are sorely out of sync.

常见的影响
| 范围 | 影响 | 注释 |
|---|---|---|
| Access Control | Gain Privileges or Assume Identity | Trust may be assigned to an entity who is not who it claims to be. |
| ['Integrity', 'Other'] | Other | Data from an untrusted (and possibly malicious) source may be integrated. |
| Confidentiality | Read Application Data | Data may be disclosed to an entity impersonating a trusted entity, resulting in information disclosure. |
可能的缓解方案
Architecture and Design
策略:
Ensure that certificates are checked for revoked status.
Implementation
策略:
If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the revoked status.
示例代码
例
The following OpenSSL code ensures that there is a certificate before continuing execution.
bad C
// got a certificate, do secret things
Because this code does not use SSL_get_verify_results() to check the certificate, it could accept certificates that have been revoked (X509_V_ERR_CERT_REVOKED). The software could be communicating with a malicious host.
