CVE-2022-4967

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).
