CVE-2025-56311Public exploitNetwork attack vector

Forced reboot via unprotected administrative POST

Published Sep 23, 2025 · Updated Sep 23, 2025

Cross-site request forgery in Shenzhen C-Data Technology Co. FD602GW-DX-R410 2.2.14 allows remote attackers to reboot the router. The /boaform/admin/formReboot handler accepts a cross-origin POST containing postSecurityFlag=+65535 without a CSRF token or Origin validation. Exploitation requires an authenticated administrator to visit an attacker-controlled page, after which the accepted request immediately reboots the device and interrupts network service.
