Summary
Logic vulnerability in TP-Link Archer C20 v5, 6.0, Archer AX53 v1.0 and TL-WR841N v13 (TDDP module) allows unauthenticated adjacent attackers to execute administrative commands including factory reset and device reboot without credentials. Attackers on the adjacent network can remotely trigger factory resets and reboots without credentials, causing configuration loss and interruption of device availability.
This issue affects Archer C20 v6.0 < V6_251031, Archer C20 v5 <EU_V5_260317 or < US_V5_260419
Archer AX53 v1.0 <
V1_251215
TL-WR841N v13 < 0.9.1 Build 20231120 Rel.62366
