Cisco Unified MeetingPlace Web Conferencing Cross-Site Scripting Vulnerability

A vulnerability in the web framework of Cisco Unified MeetingPlace could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against users of the web interface on the affected system. The vulnerability is due to insufficient input validation of a parameter. An attacker could exploit this vulnerability by convincing a user to access a malicious link. Cisco has confirmed this vulnerability in a security notice; however, software updates are not available. 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. Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.

Administrators are advised to contact the vendor regarding future updates and releases.

Users should verify that unsolicited links are safe to follow.
