Descriptions

Multiple vulnerabilities in the authentication mechanisms 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. For more information about these vulnerabilities, see the Details section of this advisory.

Múltiples vulnerabilidades en los mecanismos de autenticación de Cisco Data Center Network Manager (DCNM), podrían permitir a un atacante remoto no autenticado omitir la autenticación y ejecutar acciones arbitrarias con privilegios administrativos sobre un dispositivo afectado. Para más información sobre estas vulnerabilidades, véase la sección Detalles de este aviso.

This vulnerability allows remote attackers to bypass authentication on affected installations of Cisco Data Center Network Manager. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the validation of SSO tokens of SOAP packets. The issue results from the use of a hard-coded key to validate the message digest. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of SYSTEM.

Cisco Data Center Network Manager version 11.2.1 suffers from a remote SQL injection vulnerability.
