Cisco Unity Connection Reflected Cross-Site Scripting Vulnerability

Published Apr 15, 2026 · Updated Apr 15, 2026 · Assigned by cisco

Description

A vulnerability in the web-based management interface of Cisco Unity Connection could allow an unauthenticated, remote attacker to conduct a reflected XSS attack against a user of the interface.

This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.
