Descriptions

A vulnerability in the session validation feature of Cisco Data Center Network Manager (DCNM) could allow an unauthenticated, remote attacker to bypass access controls and conduct a server-side request forgery (SSRF) attack on a targeted system. This vulnerability is due to insufficient validation of parameters in a specific HTTP request by an attacker. An attacker could exploit this vulnerability by sending a crafted HTTP request to an authenticated user of the DCNM web application. A successful exploit could allow the attacker to bypass access controls and gain unauthorized access to the Device Manager application, which provides access to network devices managed by the system.

Una vulnerabilidad en la funcionalidad de comprobación de sesión de Cisco Data Center Network Manager (DCNM), podría permitir a un atacante no autenticado remoto omitir los controles de acceso y conducir un ataque de tipo server-side request forgery (SSRF) en un sistema objetivo. Esta vulnerabilidad es debido a una comprobación insuficiente de los parámetros en una petición HTTP específica por parte de un atacante. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición HTTP diseñada hacia un usuario autenticado de la aplicación web de DCNM. Una explotación con éxito podría permitir al atacante omitir los controles de acceso y conseguir acceso no autorizado a la aplicación Device Manager, que proporciona acceso a los dispositivos de red administrados por el sistema
