CVE-2023-39366Public exploitNetwork attack vector

Account takeover via unescaped device name

Published Sep 5, 2023 · Updated Feb 13, 2025

Stored XSS in The Cacti Group's Cacti 1.2.24 and earlier allows remote authenticated users to execute JavaScript in a privileged user's browser. The data_sources.php form passes a database-backed device name to layout.js, whose textBoxWidth function inserts the value into an HTML string and appends it to the DOM without escaping. General Administration Sites/Devices/Data permission is required to store the payload, and a same- or higher-privileged user must open the affected data-source view, enabling victim-account takeover or actions as that user.
