Descriptions

A vulnerability in the web-based management interface of Cisco Data Center Network Manager (DCNM) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by intercepting a request from a user and injecting malicious data into an HTTP header. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive browser-based information.

Una vulnerabilidad en la interfaz de administración basada en web de Cisco Data Center Network Manager (DCNM), podría permitir a un atacante remoto no autenticado dirigir un ataque de tipo cross-site scripting (XSS) contra un usuario de la interfaz. La vulnerabilidad se presenta porque la interfaz de administración basada en web no comprueba apropiadamente la entrada suministrada por parte del usuario. Un atacante podría explotar esta vulnerabilidad al interceptar una petición de un usuario e inyectar datos maliciosos en un encabezado HTTP. Una explotación con éxito podría permitir al atacante ejecutar código script arbitrario en el contexto de la interfaz afectada o acceder a información confidencial basada en navegador
