Description
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.
