- CWE-798 - Use of Hard-coded Credentials
Summary
A hardcoded credential
vulnerability exists in the firmware of multiple TP-Link routers (TL-WR845N v4, TL-WR850N v3, TL-WR902AC v4, Archer C20 v6 & Archer MR200 v5). Authentication-related credential material is
embedded within a password file in the firmware image and may be recovered
through firmware analysis.
Successful
exploitation could result in unauthorized access to privileged functions on
affected devices.

CWE
- CWE-312 - Cleartext storage of sensitive information
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.
