Vulnerability Description
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.
