Descriptions

Cisco Secure Access Control Server for Windows (ACS Windows) and Cisco Secure Access Control Server Solution Engine (ACS Solution Engine) 3.3.1, when the EAP-TLS protocol is enabled, does not properly handle expired or untrusted certificates, which allows remote attackers to bypass authentication and gain unauthorized access via a "cryptographically correct" certificate with valid fields such as the username.

Cisco Secure Access Control Server para Windows (ACS Windows) y Cisco Secure Access Control Server Solution Engine (ACS Solution Engine) 3.3.1 cuando el protocolo EAP-TLS está permitido, no maneja adecuadamente certificados expirados o no confiables, lo que permite a atacantes remotos saltarse autenticación y ganar acceso no autorizado mediante un certificado "criptográficamente correcto" con campos válidos, como el nombre de usuario.
