Teltonika Networks has recently identified a critical firmware vulnerability in its TRB1-series devices. To ensure your devices’ security, we highly recommend you update their firmware to version TRB1_R_00.07.05.2 or newer.


We have recently identified a firmware vulnerability in our TRB1-series devices. This vulnerability can only be exploited through LAN access via Ethernet or USB interfaces and does not affect devices remotely via mobile networks. It affects the TRB140, TRB141, TRB142, TRB143, and TRB145 industrial gateways across all firmware versions before TRB1_R_00.07.05.2.  

Version TRB1_R_00.07.05.2 of the firmware has resolved this issue, so we highly recommend you update the firmware of your TRB1-series devices to the latest version to ensure the continued secure operation of your devices. You can download and install firmware updates from our Wiki page, FOTA, or RMS. Regularly updating your devices’ firmware to the latest version is essential to keeping it secure. 

As always, Teltonika Networks is committed to transparency regarding such issues and to ensuring the security and reliability of its products. For further assistance or advice on updating the firmware, please reach out to our technical support Helpdesk.
