**Name of the Vulnerable Software and Affected Versions** HG100 firmware versions up to 4.00.06 **Description** A broken access control issue allows an attacker in the same local area network to control IoT devices without authentication by accessing the `http://[target]/smarthome/devicecontrol` endpoint. **Recommendations** For HG100 firmware versions up to 4.00.06, update to a version later than 4.00.06 to resolve the issue. As a temporary workaround, consider restricting access to the `http://[target]/smarthome/devicecontrol` endpoint to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** SmartHome app (Android versions up to 3.0.42 190515) SmartHome app (iOS versions up to 2.0.22) **Description** A broken access control issue allows an attacker in the same local area network to list user accounts and control IoT devices connected to the HG100 gateway via the "http://[target]/smarthome/devicecontrol" endpoint without any authentication. **Recommendations** For Android versions up to 3.0.42 190515, update to a version later than 3.0.42 190515 to resolve the issue. For iOS versions up to 2.0.22, update to a version later than 2.0.22 to resolve the issue. As a temporary workaround, consider restricting access to the "http://[target]/smarthome/devicecontrol" endpoint to minimize the risk of exploitation.
