Descriptions

A vulnerability in the REST API of Cisco Data Center Network Manager (DCNM) could allow an unauthenticated, remote attacker to bypass authentication and execute arbitrary actions with administrative privileges on an affected device. The vulnerability exists because different installations share a static encryption key. An attacker could exploit this vulnerability by using the static key to craft a valid session token. A successful exploit could allow the attacker to perform arbitrary actions through the REST API with administrative privileges.

Una vulnerabilidad en la API REST de Cisco Data Center Network Manager (DCNM), podría permitir a un atacante remoto no autenticado omitir la autenticación y ejecutar acciones arbitrarias con privilegios administrativos sobre un dispositivo afectado. La vulnerabilidad se presenta porque las diferentes instalaciones comparten una clave de cifrado estático. Un atacante podría explotar esta vulnerabilidad utilizando la clave estática para crear un token de sesión válido. Una explotación con éxito podría permitir al atacante llevar a cabo acciones arbitrarias por medio de la API REST con privilegios administrativos
