CVE-2023-7328Public exploitNetwork attack vector

Unauthenticated user data disclosure via management API

Published Nov 14, 2025 · Updated Apr 7, 2026

Missing authentication in the user management API of DB Elettronica SFT DAB 600/C 1.9.3 and earlier allows remote attackers to read user data. The /system/api/userManager.cgx endpoint accepts an unauthenticated HTTP GET and returns JSON containing users, roles, session state, client IPs, and timeouts. Network access to the transmitter's HTTP management service is sufficient, and the demonstrated consequence is limited to disclosure of that data.
