Cisco Unified Communications Manager IPMA Cross-Site Scripting Vulnerability

A vulnerability in the Cisco IP Manager Assistant (IPMA) interface of Cisco Unified Communications Manager (UCM) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web interface on the affected system.

The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by convincing 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.
