Cisco Jabber Guest Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco Jabber Guest 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 device.

The vulnerability exists because the web-based management interface of the affected device does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user 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 to access sensitive, browser-based information.

There are no workarounds that address this vulnerability.
