The ocsp_check function in rlm_eap_tls.c in FreeRADIUS 2.1.11, when OCSP is enabled, does not properly parse replies from OCSP responders, which allows remote attackers to bypass authentication by using the EAP-TLS protocol with a revoked X.509 client certificate.
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
