Descriptions

A vulnerability in the web-based management interface of Cisco Data Center Network Manager (DCNM) could allow an authenticated, remote attacker with administrative credentials to conduct a cross-site scripting (XSS) attack against a user of the interface. The vulnerability is due to insufficient input validation by the web-based management interface. An attacker could exploit this vulnerability by inserting malicious data into a specific data field in the interface. 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. To exploit this vulnerability, the attacker would need administrative credentials on the affected device.

La vulnerabilidad es debido a una comprobación de entrada insuficiente por parte de la interfaz de administración basada en web. Un atacante podría explotar esta vulnerabilidad al insertar datos maliciosos en un campo de datos específico en la interfaz. Una explotación con éxito podría permitir a un atacante ejecutar código script arbitrario en el contexto de la interfaz afectada o acceder a información confidencial basada en el navegador. Para explotar esta vulnerabilidad, el atacante necesitaría credenciales administrativas en el dispositivo afectado
