CVE-2022-4967 (opens in a new tab)How to fix?
Upgrade Debian:12 strongswan to version 5.9.6-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream strongswan package and not the strongswan package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
strongSwan versions 5.9.2 through 5.9.5 are affected by authorization bypass through improper validation of certificate with host mismatch (CWE-297). When certificates are used to authenticate clients in TLS-based EAP methods, the IKE or EAP identity supplied by a client is not enforced to be contained in the client's certificate. So clients can authenticate with any trusted certificate and claim an arbitrary IKE/EAP identity as their own. This is problematic if the identity is used to make policy decisions. A fix was released in strongSwan version 5.9.6 in August 2022 (e4b4aabc4996fc61c37deab7858d07bc4d220136).
