CVE-2022-27630Public exploit

Wi-Fi credential disclosure via unparsed protobuf request

Published Aug 5, 2022 · Updated Apr 15, 2025

Information disclosure in TCL LINKHUB Mesh Wi-Fi AC1200 MS1G_00_01.00_14 allows attackers to read the Wi-Fi SSID and password. The confctl_get_master_wlan handler performs no protobuf parsing before wlan_get_master_cfg returns plaintext configuration fields. Unauthenticated access to port 9003 from the router's wireless or wired network is sufficient, and the reported consequence is credential disclosure.
