Descriptions

A vulnerability in the CLI of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, local attacker to access the shell of the underlying Linux operating system on the affected device. The vulnerability is due to improper input validation in the affected software. An attacker could exploit this vulnerability by sending crafted commands to the affected device. An exploit could allow the attacker to gain shell access with a nonroot user account to the underlying Linux operating system on the affected device and potentially access system configuration files with sensitive information. This vulnerability only affects console connections from CIMC. It does not apply to remote connections, such as telnet or SSH.

Una vulnerabilidad en la interfaz de línea de comandos (CLI) de Cisco Enterprise NFV Infrastructure Software (NFVIS) podría permitir que un atacante remoto autenticado aceda al shell del sistema operativo Linux en el dispositivo afectado. La vulnerabilidad se debe a la insuficiente validación de entradas por parte del software afectado. Un atacante podría explotar esta vulnerabilidad enviando comandos manipulados al dispositivo afectado. Su explotación con éxito podría permitir que el atacante obtenga acceso shell con una cuenta de usuario que no es root al sistema operativo Linux subyacente en el dispositivo afectado y acceda a los archivos de configuración del sistema con información sensible. Esta vulnerabilidad solo afecta a las conexiones de consola desde CIMC. No aplica a las conexiones remotas, como telnet o SSH.
