Summary

The vulnerability affecting TL-WR850N v3 allows cleartext storage of administrative and Wi-Fi credentials in a region of the device’s flash memory while the serial interface remains enabled and protected by weak authentication. An attacker with physical access and the ability to connect to the serial port can recover sensitive information, including the router’s management password and wireless network key. Successful exploitation can lead to full administrative control of the device and unauthorized access to the associated wireless network.
