Technical details

The authorization middleware in the HTTP API and WebSocket endpoints fails to validate authentication tokens, allowing unauthenticated access from the local network. An attacker with LAN access can directly query these endpoints to extract system information and issue raw control commands to manipulate building automation devices. The vulnerability was patched in version 3.0.30.
