Descriptions

A vulnerability in the Cisco SD-WAN Solution could allow an authenticated, remote attacker to overwrite arbitrary files on the underlying operating system of an affected device. The vulnerability is due to improper input validation of the save command in the CLI of the affected software. An attacker could exploit this vulnerability by modifying the save command in the CLI of an affected device. A successful exploit could allow the attacker to overwrite arbitrary files on the underlying operating system of an affected device and escalate their privileges to the root user.

Una vulnerabilidad en la solución Cisco SD-WAN podría permitir a un atacante remoto autenticado sobrescribir archivos arbitrarios en el sistema operativo subyacente de un dispositivo afectado. La vulnerabilidad se debe a una validación de entrada incorrecta del comando save en la interfaz de línea de comandos (CLI) del software afectado. Un atacante podría explotar esta vulnerabilidad modificando el comando save en la CLI de un dispositivo afectado. Si se explota esta vulnerabilidad con éxito, el atacante podría sobrescribir archivos arbitrarios en el sistema operativo subyacente de un dispositivo afectado y escalar sus privilegios a usuario root.
