CVE-2022-27185Public exploit

Service interruption via unauthenticated WLAN reconfiguration

Published Aug 5, 2022 · Updated Apr 15, 2025

Improper access control in TCL LINKHUB Mesh Wi-Fi AC1200 MS1G_00_01.00_14 allows adjacent attackers to interrupt service via network packets. The ucloud service accepts unauthenticated WlanCfgAll protobuf messages on TCP port 9003, and confctl_set_master_wlan writes supplied SSIDs and passwords directly into the 2.4 GHz or 5 GHz configuration. Access to the router-provided Wi-Fi or wired network is required, and changing those credentials can disconnect clients and alter network access.
