## Mitigation

### Recommended Actions

1. **Firmware Update**: Update affected devices to version **3.1.1 Build 251124 Rel.50371n** or later.

2. **Network Isolation**: If possible, place VIGI C385 devices in an isolated network segment.

3. **Access Control**: Restrict access to the management interface to trusted networks only.

4. **Monitoring**: Monitor for abnormal network traffic or device behavior.

### Temporary Mitigation Measures

- Block external access to the web management interface.
- Use strong authentication credentials.
- Disable unnecessary network services.
