A story of WiFi secrets, UART lockdowns and a damaged flash memory chip

A security researcher has discovered several vulnerabilities in the Eufy HomeStation 2 Wi-Fi router, including a UART lockdown bug and a damaged flash memory chip. The researcher found that the router's firmware can be modified by exploiting a bug in the UART, allowing for remote code execution. The firmware can also be switched to a different version by modifying a single byte in the flash memory chip. The researcher has released a proof-of-concept exploit code and provided instructions on how to modify the firmware.
