This vulnerability exists in TP-Link IoT Smart Hub due to storage of Wi-Fi credentials in plain text within the device firmware. An attacker with physical access could exploit this by extracting the firmware and analyzing the binary data to obtain the Wi-Fi credentials stored on the vulnerable device.
This vulnerability exists in the TP-Link Archer C50 due to presence of terminal access on a serial interface without proper access control. An attacker with physical access could exploit this by accessing the UART shell on the vulnerable device. Successful exploitation of this vulnerability could allow the attacker to obtain Wi-Fi credentials of the targeted system.
