Teltonika Networks has released an important firmware update for its TRB14x series gateways (TRB140, TRB141, TRB142, TRB143 and TRB145) that addresses a potentially serious security breach. This security breach can only be exploited through a local area network (LAN) port using an Ethernet or USB interface and does not affect devices remotely over cellular networks. To ensure maximum network and data security, we recommend updating the firmware to version 'TRB1_R_00.07.05.4', which is available for download on the Teltonika Wiki Page.
It is recommended to update your device gradually in smaller batches to minimize potential problems.
