CVE-2022-41505Public exploit

Physical root access via mutable UART boot parameters

Published Jan 23, 2023 · Updated Apr 3, 2025

Missing authorization in TP-Link Tapo C200 V1 allows physically proximate attackers to obtain a root shell through its UART interface. The exposed bootloader accepts an interrupted autoboot sequence and permits the init environment value to be changed to /bin/sh before bootcmd runs. Physical access to the camera and knowledge of the autoboot interruption key are required; the resulting root shell permits firmware extraction and arbitrary command execution.
