Descriptions

A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker with administrative privileges to execute arbitrary code with root privileges on the underlying Linux shell. The vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by first creating a malicious file on the affected device itself and then uploading a second malicious file to the device. A successful exploit could allow the attacker to execute arbitrary code with root privileges or bypass licensing requirements on the device.

Una vulnerabilidad en la Interfaz de Usuario web de Cisco IOS XE Software, podría permitir a un atacante remoto autenticado con privilegios administrativos ejecutar código arbitrario con privilegios root en el shell de Linux subyacente. La vulnerabilidad es debido a una comprobación inapropiada de la entrada suministrada por el usuario. Un atacante podría explotar esta vulnerabilidad al crear primero un archivo malicioso sobre el dispositivo afectado y luego cargando un segundo archivo malicioso sobre el dispositivo. Una explotación con éxito podría permitir al atacante ejecutar código arbitrario con privilegios root u omitir los requisitos de licencia en el dispositivo.
