The vulnerability is due to the presence of a proxy service at a specific endpoint of the web UI. An attacker could exploit this vulnerability by connecting to the proxy service. An exploit could allow the attacker to bypass access restrictions on the network by proxying their access request through the management network of the affected device. As the proxy is reached over the management virtual routing and forwarding (VRF), this could reduce the effectiveness of the bypass."}, {"lang": "es", "value": "Una vulnerabilidad en la interfaz de usuario basada en web (UI web) de Cisco IOS XE Software, podr\u00eda permitir a un atacante adyacente no autenticado omitir las restricciones de control de acceso sobre un dispositivo afectado.
