CWE-79
Summary
A vulnerability in the web-based management interface of Cisco Unified
Contact Center Express could allow an unauthenticated, remote attacker
to conduct a cross-site scripting (XSS) attack against a user of an
affected device.
The vulnerability is due to insufficient validation of user-supplied
input by the web-based management interface of the affected device. An
attacker could exploit this vulnerability by persuading a user of the
interface to click a malicious link. A successful exploit could allow
the attacker to execute arbitrary script code in the context of the
interface or allow the attacker to access sensitive browser-based
information.

be found at the following links:
