Descriptions

A vulnerability in a CLI command related to the virtualization manager (VMAN) in Cisco IOS XR Software for Cisco ASR 9000 Series Aggregation Services Routers could allow an authenticated, local attacker to execute arbitrary commands on the underlying Linux operating system with root privileges. The vulnerability is due to insufficient validation of arguments passed to a specific VMAN CLI command on an affected device. An attacker who has valid administrator access to an affected device could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to run arbitrary commands on the underlying operating system with root privileges, which may lead to complete system compromise.

Una vulnerabilidad en un comando de la CLI relacionado con el virtualization manager (VMAN) en el Software Cisco IOS XR, para Cisco ASR 9000 Series Aggregation Services Routers, podría permitir a un atacante local autenticado ejecutar comandos arbitrarios en el sistema operativo Linux subyacente con privilegios root. La vulnerabilidad es debido a una comprobación insuficiente de los argumentos pasados ??a un comando específico de la CLI de VMAN en un dispositivo afectado. Un atacante que tenga acceso válido de administrador a un dispositivo afectado podría explotar esta vulnerabilidad mediante la inclusión de entradas maliciosas como argumento de un comando afectado. Una explotación con éxito podría permitir al atacante ejecutar comandos arbitrarios en el sistema operativo subyacente con privilegios root, lo que puede conllevar a un compromiso total del sistema.
