Descriptions
A vulnerability in the SSH client feature of Cisco IOS XR Software for Cisco 8000 Series Routers and Cisco Network Convergence System (NCS) 540 Series and 5700 Series Routers could allow an authenticated, local attacker to elevate privileges on an affected device.
This vulnerability is due to insufficient validation of arguments that are included with the SSH client CLI command. An attacker with low-privileged access to an affected device could exploit this vulnerability by issuing a crafted SSH client command to the CLI. A successful exploit could allow the attacker to elevate privileges to root on the affected device.
Una vulnerabilidad en la función de cliente SSH del software Cisco IOS XR para los enrutadores Cisco de la serie 8000 y los enrutadores Cisco Network Convergence System (NCS) de las series 540 y 5700 podría permitir que un atacante local autenticado eleve los privilegios en un dispositivo afectado. Esta vulnerabilidad se debe a una validación insuficiente de los argumentos que se incluyen con el comando CLI del cliente SSH. Un atacante con acceso con pocos privilegios a un dispositivo afectado podría aprovechar esta vulnerabilidad emitiendo un comando de cliente SSH manipulado a la CLI. Un exploit exitoso podría permitir al atacante elevar los privilegios a root en el dispositivo afectado.
