Descriptions

A vulnerability in the Common Access Card (CAC) authentication feature of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to bypass authentication and access the FMC system. The attacker must have a valid CAC to initiate the access attempt. The vulnerability is due to incorrect session invalidation during CAC authentication. An attacker could exploit this vulnerability by performing a CAC-based authentication attempt to an affected system. A successful exploit could allow the attacker to access an affected system with the privileges of a CAC-authenticated user who is currently logged in.

Una vulnerabilidad en la funcionalidad de autenticación Common Access Card (CAC) de Cisco Firepower Management Center (FMC) Software, podría permitir a un atacante remoto no autenticado omitir la autenticación y acceder al sistema FMC. El atacante debe tener un CAC válido para iniciar el intento de acceso. La vulnerabilidad es debido a una incorrecta invalidación de la sesión durante la autenticación CAC. Un atacante podría explotar esta vulnerabilidad al llevar a cabo un intento de autenticación basado en CAC en un sistema afectado. Una explotación con éxito podría permitir a un atacante acceder a un sistema afectado con los privilegios de un usuario autenticado por CAC que actualmente está conectado
