CVE-2024-57049 affects TP-Link Archer C20 routers running firmware V6.6_230412 and earlier. According to the provided description, some interfaces under the /cgi path can be accessed without proper authentication if the HTTP request includes the header Referer: http://tplinkwifi.net. The device incorrectly treats the presence of this Referer value as evidence that authentication has already been satisfied, resulting in an authentication bypass condition for those endpoints. The issue is disputed by the supplier, which states that the affected API response exposes only non-sensitive UI initialization variables; however, based on the provided information, the reported weakness is an authentication decision made on the basis of a spoofable request header rather than a robust authentication mechanism.
