Remediations

Vendor fix
Labkotec reports that it is not possible to implement secure and encrypted network traffic on the LID-3300IP. For this reason, Labkotec recommends updating ice detectors to the LID-3300IP Type 2 model and installing the latest firmware version V2.40. It is also highly recommended to activate HTTPS for network traffic. The device type and software version can be verified in the web interface.

Mitigation
Devices not connected to an Ethernet network are not susceptible to this attack. Ice detectors operating on secure internal networks that adhere to modern security standards, where only authorized devices and users have access, are protected against external threats.

Mitigation
Labkotec recommends implementing the following additional security controls:
Do not connect the device to the public Internet
Follow good security practices
Change Default Credentials
Enable Secure Management Access
Network Segmentation
Implement Firewall and Access Controls
Restrict Protocols
Monitor and Alert
Avoid Direct Internet Exposure
Keep Firmware Updated
Control Physical Access
Maintain Inventory and Access Reviews

Mitigation
