The vulnerability is due to insufficient identity verification of the KDC when a successful authentication response is received. An attacker could exploit this vulnerability by spoofing the KDC server response to the ASA device. This malicious response would not have been authenticated by the KDC. A successful attack could allow an attacker to bypass Kerberos authentication."},{"lang":"es","value":"Una vulnerabilidad en la funcionalidad de autenticación de Kerberos del Cisco Adaptive Security Appliance (ASA) Software, podría permitir a un atacante remoto no autenticado suplantar al centro de distribución de claves (KDC) de Kerberos y omitir la autenticación sobre un dispositivo afectado que esté configurado para realizar la autenticación Kerberos para VPN o acceso local a dispositivos. La vulnerabilidad es debido a una verificación de identidad insuficiente del KDC cuando es recibida una respuesta de autenticación con éxito. Un atacante podría explotar esta vulnerabilidad al suplantar la respuesta del servidor KDC en el dispositivo ASA. Esta respuesta maliciosa no habría sido autenticada por el KDC.
