Firmware-signature bypass via hidden console command

Published Nov 9, 2022 · Updated Apr 15, 2025

Leftover debug code in InHand Networks InRouter302 3.5.45 allows remote authenticated users to disable firmware-signature verification. The hidden console verify command accepts the disable argument and turns off the firmware signature check. Access requires valid Telnet or SSH console credentials; disabling verification permits firmware without an enforced signature check.
