DescriptionOpenBK7231T's /cfg_wifi_set endpoint (src/httpserver/http_fns.c) accepts configuration changes via a plain GET request with no CSRF token. If the `web_admin_password_enabled` parameter is absent from the request, an else-branch silently clears the device's web admin password to an empty string. A one-click CSRF payload (e.g. an <img> tag pointing at /cfg_wifi_set with new SSID/password parameters and web_admin_password_enabled omitted) visited by an authenticated admin's browser both hijacks the device's WiFi configuration and disables its web password protection.
