Cisco Unified Communications Manager DNA Cross-Site Scripting Vulnerability

A vulnerability in the Dialed Number Analyzer (DNA) of Cisco Unified Communications Manager could allow an unauthenticated, remote attacker to
perform a cross-site scripting (XSS) attack against the user of a web interface.

The vulnerability is due to insufficient input validation of a parameter in the viewfilecontents.do page. An attacker could exploit this
vulnerability by persuading a user to access a malicious link.

Cisco has confirmed the 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.
