Weakness (CWE)
CWE-295: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How to prevent it (2 mitigations)
-
Architecture and Design, Implementation
Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
-
Implementation
If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
