CWE-ID: CWE-295 - Improper Certificate Validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to bypass certificate validation on the target system.
The vulnerability exists due to CN validation error. A remote unauthenticated attacker can bypass certificate validation on the target system by supplying a specially crafted self-signed certificate with a spoofed Common Name (CN) value that matches a valid certificate authority (CA).
This issue only affects certificates used for IKE/IPsec. Other public key-based authentication is unaffected by this vulnerability.
Successful exploitation of this vulnerability may result in host/resource access.
