The vulnerability exists because the affected software has insufficient authentication mechanisms for certain commands. An attacker could exploit this vulnerability by requesting access to the root shell of an affected device, after the shell access feature has been enabled. A successful exploit could allow the attacker to bypass authentication and gain unrestricted access to the root shell of the affected device."}, {"lang": "es", "value": "Una vulnerabilidad en el mecanismo de petici\u00f3n de acceso al shell de Cisco IOS XE Software podr\u00eda permitir que un atacante local autenticado omita la autenticaci\u00f3n y obtenga acceso sin restricciones al shell root de un dispositivo afectado. La vulnerabilidad existe debido a que el software afectado tiene mecanismos de autenticaci\u00f3n insuficientes para ciertos comandos. Un atacante podr\u00eda explotar esta vulnerabilidad solicitando acceso al shell root de un dispositivo afectado, una vez se ha habilitado la funcionalidad de acceso al shell.
