Cisco Prime Infrastructure and Evolved Programmable Network Manager DOM Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco Prime Infrastructure (PI) and Evolved Programmable Network Manager (EPNM) could allow an unauthenticated, remote attacker to conduct a Document Object Model (DOM) based (environment or client-side) cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device.

The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive browser-based information.
