Descriptions

A vulnerability in authentication mechanism of Cisco Software-Defined Application Visibility and Control (SD-AVC) on Cisco vManage could allow an unauthenticated, remote attacker to access the GUI of Cisco SD-AVC without authentication. This vulnerability exists because the GUI is accessible on self-managed cloud installations or local server installations of Cisco vManage. An attacker could exploit this vulnerability by accessing the exposed GUI of Cisco SD-AVC. A successful exploit could allow the attacker to view managed device names, SD-AVC logs, and SD-AVC DNS server IP addresses.

Una vulnerabilidad en el mecanismo de autenticación de Cisco Software-Defined Application Visibility and Control (SD-AVC) en Cisco vManage podría permitir a un atacante remoto no autenticado acceder a la GUI de Cisco SD-AVC sin autenticación. Esta vulnerabilidad se presenta porque la GUI es accesible en instalaciones autoadministradas en la nube o en instalaciones de servidores locales de Cisco vManage. Un atacante podría explotar esta vulnerabilidad al acceder a la GUI expuesta de Cisco SD-AVC. Una explotación con éxito podría permitir al atacante visualizar los nombres de los dispositivos administrados, los registros de SD-AVC y las direcciones IP del servidor DNS de SD-AVC
