Description
The response coming from TP-Link Archer MR200 v5.2, C20 v5 and v6, TL-WR850N v3, and TL-WR845N v4 for any request is getting executed by the JavaScript function like eval directly without any check. Attackers can exploit this vulnerability via a Man-in-the-Middle (MitM) attack to execute JavaScript code on the router's admin web portal without the user's permission or knowledge.
