CVE-2022-22144Public exploit

Root access via startup-forced hard-coded password

Published Aug 5, 2022 · Updated Apr 15, 2025

Hard-coded credentials in TCL LINKHUB Mesh Wi-Fi AC1200 MS1G_00_01.00_14 allow remote attackers to authenticate as root with a known password. At every boot, netctrl calls libcommonprod.so's prod_change_root_passwd without a condition, and the function pipes a fixed string into passwd. No user action or prior privilege is required, but exploitation depends on adjacent reachability to a root-authentication service on the mesh appliance.
