Measurement devices and IoT gateways.

Units running V1.00 or later shipped through October 22 may be affected; a fix is being considered. The vendor states that measures were applied to shipments from October 23.

Scope: SORACOM/Napter access with the specified SIM lowers direct exposure; it does not prove immunity. Check customer SIM, public IP and port settings separately.

What users should do

Check shipment date and exposure; restrict access using firewall, VPN and source-IP controls. Watch for a fix announcement.
