Administrator takeover via unauthenticated hidden reset form
Published Sep 14, 2025 · Updated Sep 15, 2025
Missing authentication in LG Electronics AC Smart II 2.1.9 allows remote attackers on an adjacent network to reset the administrator password. The web interface embeds a hidden administrator-password reset form and processes it without checking login status or user permissions. Network reachability to the controller is sufficient to replace the administrator credential, lock out its legitimate holder, and gain control of connected devices.
