Technical description

A vulnerability in the web-based management interface of Cisco Unified Contact Center Express (Unified CCX) could allow an authenticated, remote attacker to perform a stored cross-site scripting (XSS) attack. This vulnerability is due to insufficient input validation of user-supplied data. An attacker could exploit this vulnerability by entering crafted text into various input fields within the web-based management interface. A successful exploit could allow the attacker to perform a stored XSS attack, which could allow the execution of scripts within the context of other users of the interface.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
