A cross-site scripting (XSS) filter bypass vulnerability in the web-based management interface of Cisco Unified Communications Manager could allow an unauthenticated, remote attacker to mount XSS attacks against a user of an affected device. 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.
