Descriptions
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.
La función ocsp_check de rlm_eap_tls.c de FreeRADIUS 2.1.11, si OCSP está habilitado, no analiza correctamente la sintaxis ("parse") de las respuestas de los agentes transmisores OCSP, lo que permite a atacantes remotos evitar la autenticación usando el protocolo EAP-TLS con un certificado cliente X.509 revocado.
