Descriptions

A vulnerability in Cisco Application Policy Infrastructure Controller (APIC) could allow an authenticated, remote attacker to gain higher privileges than the account is assigned. The attacker will be granted the privileges of the last user to log in, regardless of whether those privileges are higher or lower than what should have been granted. The attacker cannot gain root-level privileges. The vulnerability is due to a limitation with how Role-Based Access Control (RBAC) grants privileges to remotely authenticated users when login occurs via SSH directly to the local management interface of the APIC. An attacker could exploit this vulnerability by authenticating to the targeted device. The attacker's privilege level will be modified to match that of the last user to log in via SSH. An exploit could allow the attacker to gain elevated privileges and perform CLI commands that should be restricted by the attacker's configured role. Cisco Bug IDs: CSCvc34335. Known Affected Releases: 1.0(1e), 1.0(1h), 1.0(1k), 1.0(1n), 1.0(2j), 1.0(2m), 1.0(3f), 1.0(3i), 1.0(3k), 1.0(3n), 1.0(4h), 1.0(4o); 1.1(0.920a), 1.1(1j), 1.1(3f); 1.2 Base, 1.2(2), 1.2(3), 1.2.2; 1.3(1), 1.3(2), 1.3(2f); 2.0 Base, 2.0(1).

Una vulnerabilidad en Cisco Application Policy Infrastructure Controller (APIC) podría permitir que un atacante remoto autenticado obtenga privilegios más altos que los que se han asignado a la cuenta. El atacante tendrá los privilegios del último usuario que haya iniciado sesión, independientemente de si esos privilegios son mayores o menores que los que se deberían haber dado. El atacante no puede obtener permisos root. La vulnerabilidad se debe a una limitación en la forma en la que Role-Based Access Control (RBAC) concede permisos a usuarios autenticados de forma remota cuando el inicio de sesión ocurre directamente mediante SSH directamente en la interfaz de gestión local. Un atacante podría explotar esta vulnerabilidad autenticándose en el dispositivo objetivo. El nivel de privilegios del atacante será modificado para coincidir con el del último usuario que haya iniciado sesión por SSH. Un exploit podría permitir que el atacante obtenga privilegios elevados y realizar comandos CLI que deberían estar restringidos por el rol configurado del atacante. Cisco Bug IDs: CSCvc34335. Versiones afectadas conocidas: 1.0(1e), 1.0(1h), 1.0(1k), 1.0(1n), 1.0(2j), 1.0(2m), 1.0(3f), 1.0(3i), 1.0(3k), 1.0(3n), 1.0(4h), 1.0(4o); 1.1(0.920a), 1.1(1j), 1.1(3f); 1.2 Base, 1.2(2), 1.2(3), 1.2.2; 1.3(1), 1.3(2), 1.3(2f); 2.0 Base, 2.0(1).
