Descriptions

A vulnerability in the CLI of Cisco IOS XE Software for Cisco Catalyst 9000 Family Switches and Cisco Catalyst 9000 Family Wireless Controllers could allow an authenticated, local attacker to elevate privileges to level 15 on an affected device. This vulnerability is due to insufficient validation of user privileges after the user executes certain CLI commands. An attacker could exploit this vulnerability by logging in to an affected device as a low-privileged user and then executing certain CLI commands. A successful exploit could allow the attacker to execute arbitrary commands with level 15 privileges on the affected device.

Una vulnerabilidad en la CLI del software Cisco IOS XE para Cisco Catalyst 9000 Family Switches and Cisco Catalyst 9000 Family Wireless Controllers podría permitir a un atacante local autenticado elevar los privilegios al nivel 15 en un dispositivo afectado. Esta vulnerabilidad es debido a que no han sido comprobados suficientemente los privilegios del usuario después de que éste ejecute determinados comandos de la CLI. Un atacante podría explotar esta vulnerabilidad al iniciar sesión en un dispositivo afectado como usuario con pocos privilegios y ejecutando a continuación determinados comandos de la CLI. Una explotación con éxito podría permitir al atacante ejecutar comandos arbitrarios con privilegios de nivel 15 en el dispositivo afectado
