Descriptions

A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to inject arbitrary commands to be executed with root privileges on the underlying operating system. This vulnerability is due to insufficient input validation on certain CLI commands. An attacker could exploit this vulnerability by authenticating to the device and submitting crafted input to the CLI. The attacker must be authenticated as an administrative user to execute the affected commands. A successful exploit could allow the attacker to execute commands with root privileges.

Una vulnerabilidad en la CLI del Software Cisco IOS XE SD-WAN, podría permitir a un atacante local autenticado inyectar comandos arbitrarios para que sean ejecutados con privilegios root en el sistema operativo subyacente. Esta vulnerabilidad es debido a una comprobación insuficiente de la entrada en determinados comandos de la CLI. Un atacante podría explotar esta vulnerabilidad al autenticarse en el dispositivo y enviar una entrada diseñada a la CLI. El atacante debe estar autenticado como usuario administrativo para ejecutar los comandos afectados. Una explotación con éxito podría permitir al atacante ejecutar comandos con privilegios root
