This vulnerability occurs because the default configuration is applied for console authentication and authorization. An attacker could exploit this vulnerability by connecting to the console port and authenticating as a read-only user. A successful exploit could allow a user with read-only permissions to access administrative privileges."},{"lang":"es","value":"Una vulnerabilidad en el control de acceso basado en roles del Software Cisco IOS XE SD-WAN, podría permitir a un atacante local autenticado con privilegios de solo lectura obtener privilegios administrativos utilizando el puerto de la consola cuando el dispositivo está
