Cisco Expressway Series and TelePresence Video Communication Server Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected system.

The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of the affected system. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious 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.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
