名前: Missing Validation of OpenSSL Certificate
The product uses OpenSSL and trusts or uses a certificate without using the SSL_get_verify_result() function to ensure that the certificate satisfies all necessary security requirements.

|---|---|---|
| Confidentiality | Read Application Data 注記：The data read may not be properly secured - it might be viewed by an attacker. | |
| Access Control | Bypass Protection Mechanism, Gain Privileges or Assume Identity 注記：Trust afforded to the system in question may allow for spoofing or redirection attacks. | |
| Access Control | Gain Privileges or Assume Identity 注記：If the certificate is not checked, it may be possible for a redirection or spoofing attack to allow a malicious host with a valid certificate to provide data under the guise of a trusted host. While the attacker in question may have a valid certificate, it may simply be a valid certificate for a different site. This could allow an attacker to use an invalid certificate to claim to be a trusted host, use expired certificates, or conduct other attacks that could be detected if the certificate is properly validated. In order to ensure data integrity, we must check that the certificate is valid, and that it pertains to the site we wish to access. |
潜在的な緩和策
Phases : Architecture and DesignEnsure that proper authentication is included in the system design.
Phases : Implementation
Understand and properly implement all checks necessary to ensure the identity of entities involved in encrypted communications.
脆弱性マッピングノート
理由 : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.コメント : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
ノート
CWE-295 and CWE-599 are very similar, although CWE-599 has a more narrow scope that is only applied to OpenSSL certificates. As a result, other children of CWE-295 can be regarded as children of CWE-599 as well. CWE's use of one-dimensional hierarchical relationships is not well-suited to handle different kinds of abstraction relationships based on concepts like types of resources ("OpenSSL certificate" as a child of "any certificate") and types of behaviors ("not validating expiration" as a child of "improper validation").登録情報
