Received Received - Intake
Cross-Site Scripting in Cisco Contact Center Web Interface

Publication date: 2026-03-11

Last updated on: 2026-03-11

Assigner: Cisco Systems, Inc.

Description
A vulnerability in the web-based management interface of  Cisco Finesse, Cisco Packaged Contact Center Enterprise (Packaged CCE), Cisco Unified Contact Center Enterprise (Unified CCE), Cisco Unified Contact Center Express (Unified CCX), and Cisco Unified Intelligence Center could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface. This vulnerability exists because the web-based management interface of an affected system does not sufficiently validate user-supplied input. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. 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.

Executive Summary

This vulnerability exists in the web-based management interface of several Cisco products including Cisco Finesse, Packaged Contact Center Enterprise, Unified Contact Center Enterprise, Unified Contact Center Express, and Unified Intelligence Center.

It allows an unauthenticated, remote attacker to perform cross-site scripting (XSS) attacks by injecting malicious code into specific pages of the interface. This happens because the interface does not properly validate user-supplied input.

If successfully exploited, the attacker can execute arbitrary script code within the context of the affected interface or access sensitive information stored in the browser.

Impact Analysis

The vulnerability can impact you by allowing an attacker to execute arbitrary scripts in your web management interface without authentication.

This could lead to unauthorized access to sensitive browser-based information or manipulation of the interface, potentially compromising the security and integrity of the affected system.
