CVE-2025-65231Public exploitNetwork attack vector

Stored script execution via CTS command rendering

Published Dec 8, 2025 · Updated Dec 11, 2025

Stored XSS in Barix Instreamer 04.06 and earlier allows remote attackers to execute script in a Status-page viewer's browser. The setup.cgi interface stores the CTS close-command parameter S535 and renders it on the Status page without safe HTML encoding. CISA assesses the path as unauthenticated, but exploitation requires a user to open the Status page; the script can access or alter data available to that browser session.
