Technical Description
A vulnerability in the web-based management interface of Cisco Unity Connection Software could allow an authenticated, remote attacker to perform a stored cross-site scripting (XSS) attack. The vulnerability is due to insufficient input validation by the web-based management interface. An attacker could exploit this vulnerability by providing crafted data to a specific field within the interface. A successful exploit could allow the attacker to store an XSS attack within the interface. This stored XSS attack would then be executed on the system of any user viewing the attacker-supplied data element.
Remediation
Check the references section for vendor advisories and patches from cisco. Update unity_connection to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
