CVE-2017-6747

Estado: ModificadaCrítica (9.8)—

A vulnerability in the authentication module of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to bypass local authentication. The vulnerability is due to improper handling of authentication requests and policy assignment for externally authenticated users. An attacker could exploit this vulnerability by authenticating with a valid external user account that matches an internal username and incorrectly receiving the authorization policy of the internal account. An exploit could allow the attacker to have Super Admin privileges for the ISE Admin portal.

Esto se debe a un manejo incorrecto de las peticiones de autenticación y asignación de políticas para los usuarios autenticados externamente. Un atacante podría explotar esta vulnerabilidad autenticándose con una cuenta válida de usuario externo que coincida con un nombre de usuario interno y recibiendo de forma errónea la política de autorización de la cuenta interna. Con un exploit, el atacante podría tener privilegios de Super Admin para el portal ISE Admin. Esta vulnerabilidad no afecta a los extremos que se autentican en el ISE. Este problema afecta a Cisco ISE, Cisco ISE Express y los dispositivos virtuales de Cisco ISE que estén en sus versiones 1.3, 1.4, 2.0.0, 2.0.1 o 2.1.0. La versión 2.2.x no se ha visto afectada.
