Descriptions

A vulnerability in the web-based management interface of Cisco Prime Infrastructure (PI) and Cisco Evolved Programmable Network Manager (EPNM) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. 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 la web de Cisco Prime Infrastructure (PI) y Cisco Evolved Programmable Network Manager (EPNM) podría permitir a un atacante remoto autenticado realizar un ataque de tipo cross-site scripting (XSS) almacenado contra un usuario de la interfaz de administración basada en la web de un dispositivo afectado. Esta vulnerabilidad es debido a que la interfaz de administración basada en la web no comprueba correctamente las entradas proporcionadas por el usuario. Un atacante podría explotar esta vulnerabilidad al convencer a un usuario de la interfaz afectada para que haga clic en un enlace diseñado. Una explotación con éxito podría permitir al atacante ejecutar código de script arbitrario en el contexto de la interfaz afectada o acceder a información confidencial basada en el navegador
