Descriptions

A vulnerability in the CLI of the Cisco StarOS operating system for Cisco ASR 5000 Series Aggregation Services Routers could allow an authenticated, local attacker to perform a command injection attack on an affected system. The vulnerability is due to insufficient validation of commands that are supplied to certain configurations in the CLI of the affected operating system. An attacker could exploit this vulnerability by injecting crafted arguments into a vulnerable CLI command for an affected system. A successful exploit could allow the attacker to insert and execute arbitrary commands in the CLI of the affected system. To exploit this vulnerability, the attacker would need to authenticate to an affected system by using valid administrator credentials. Cisco Bug IDs: CSCvg29441.

Una vulnerabilidad en la interfaz de línea de comandos (CLI) del sistema operativo Cisco StarOS para routers Cisco ASR 5000 Series Aggregation Services Routers podría permitir que un atacante local autenticado realice un ataque de inyección de comandos arbitrarios en un sistema afectado. La vulnerabilidad se debe a una validación insuficiente de comandos que se proporcionan en determinadas configuraciones en el CLI del sistema afectado. Un atacante podría explotar esta vulnerabilidad inyectando argumentos manipulados en un comando de interfaz de línea de comandos vulnerable para un sistema afectado. Su explotación con éxito podría permitir que el atacante inserte y ejecute comandos arbitrarios en el CLI del sistema afectado. Para explotar esta vulnerabilidad, el atacante necesitaría autenticarse en un sistema afectado empleando credenciales de administrador válidas. Cisco Bug IDs: CSCvg29441.
