CVE-2026-38057Network attack vector

Device reboot via missing CSRF validation

Published Jul 10, 2026 · Updated Jul 10, 2026

Cross-site request forgery in ST Engineering iDirect terminals 4.5.2.1 and earlier allows remote attackers to reboot devices. The /api/reboot handler accepts cookie-authenticated POST requests without validating a CSRF token, and the session cookie lacks SameSite protection. Exploitation requires an authenticated administrator to visit attacker-controlled content; each forged request immediately reboots the terminal and drops the satellite link, while repetition sustains the interruption.
