The vulnerability is due to an improper check performed by the area of code that manages the REST API authentication service. An attacker could exploit this vulnerability by submitting malicious HTTP requests to the targeted device. A successful exploit could allow the attacker to obtain the token-id of an authenticated user. This token-id could be used to bypass authentication and execute privileged actions through the interface of the REST API virtual service container on the affected Cisco IOS XE device. The REST API interface is not enabled by default and must be installed and activated separately on IOS XE devices. See the Details section for more information."}, {"lang": "es", "value": "Una vulnerabilidad en el contenedor de servicios virtuales API REST de Cisco para el software Cisco IOS XE podr\u00eda permitir que un atacante remoto no identificado omita la autenticaci\u00f3n en el dispositivo Cisco IOS XE administrado.
