Cisco Unified Communications Manager Web Interface Cross-Site Scripting Vulnerability

Cisco Unified Communications Manager (CUCM) contains a vulnerability that could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web interface of an affected system.

The vulnerability is due to a failure to properly call XSS filter subsystems when a URL contains a certain parameter. An attacker who can persuade an authenticated user of an affected device to follow an attacker-provided link or visit an attacker-controlled website could exploit this vulnerability to execute arbitrary code in the context of the affected site in the user’s browser.

There are no workarounds that address this vulnerability.
