User InteractionNone needed
Summary

Instantel Micromate devices running firmware earlier than version 11.0BD and 11.0CB contain an unauthenticated command execution vulnerability in the configuration port. An attacker without credentials can access the port and execute arbitrary commands on the device. Instantel has released firmware updates (11.0BD, 11.0CB or later) that mitigate this issue.

What this means
What could happen
An unauthenticated attacker with network access to the Micromate device could execute arbitrary commands on it without providing credentials, potentially disrupting vibration monitoring and seismic data collection operations.
Who's at risk
Organizations using Instantel Micromate devices for seismic or vibration monitoring. This includes mining operations, construction firms, engineering consultants, and research institutions that rely on these sensors for blast monitoring or structural assessment.
How it could be exploited
An attacker on the network (or from the internet if the device is exposed) connects to the Micromate's configuration port without authentication and issues commands directly to the device. No credentials, user interaction, or special complexity is required.
Prerequisites
  • Network access to the Micromate configuration port (port number not specified in advisory)
  • Device must be reachable from attacker's network or the internet
