| Phạm vi | Tác động | Khả năng xảy ra |
|---|---|---|
| Confidentiality | Read Application Data Ghi chú: 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 Ghi chú: Trust afforded to the system in question may allow for spoofing or redirection attacks. | |
| Access Control | Gain Privileges or Assume Identity Ghi chú: 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. |

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.

Lý do : 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.Bình luận : 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.
Ghi chú
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").Gửi
