CVE-2015-4206
CWE-79
Summary
A cross-site scripting (XSS) filter bypass vulnerability in the web management
interface of Cisco Unified Communications Manager (UCM) versions 8.0 through
8.6 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 that can convince 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 on the user's
browser.
Cisco has not released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
