Cisco Jabber Guest Server contains a vulnerability that could allow an unauthenticated, remote attacker to conduct a reflected cross-site scripting (XSS) attack against the user of the web interface of the affected system.
The vulnerability is due to insufficient input validation of some parameters passed via HTTP GET or POST methods. An attacker may be able to exploit this vulnerability by intercepting user packets.
Cisco has confirmed the vulnerability in a security notice; however, software updates have not been released.
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.
