The vulnerability exist because the affected software improperly sanitizes command arguments, failing to prevent access to certain internal data structures on an affected device. An attacker who has privileged EXEC mode (privilege level 15) access to an affected device could exploit these vulnerabilities on the device by executing CLI commands that contain custom arguments. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the affected device."}, {"lang": "es", "value": "Una vulnerabilidad en el analizador CLI de Cisco IOS XE Software podr\u00eda permitir que un atacante local autenticado ejecute comandos en el shell Linux subyacente de un dispositivo afectado con privilegios root.

Un atacante que tenga acceso privilegiado en modo EXEC (nivel 15 de privilegios) a un dispositivo afectado podr\u00eda explotar estas vulnerabilidades en el dispositivo ejecutando comandos CLI que contienen argumentos personalizados.
