## Technical details

The vulnerability is an authentication bypass in the WebSocket handshake process of the Acer System Monitoring component. The service fails to properly validate authentication credentials before accepting WebSocket connections, allowing unauthorized clients to establish connections and interact with service functionality. The attack requires local network access or local system access to reach the WebSocket listener. An attacker with local access can bypass authentication controls, potentially leading to unauthorized command execution or sensitive system data exposure.
