Defensive priority

HIGH

Recommended defensive actions

  • Apply the vendor-provided remediation or updated release for the affected Fleet Management System as soon as it is available for your environment.
  • Contact Assured Telematics for the exact fixed version or deployment guidance if you cannot confirm remediation from the advisory alone.
  • Restrict access to the Fleet Management System to trusted administrative networks and users only; do not leave the service broadly reachable.
  • Rotate administrative credentials and review access logs if there is any chance the exposed information was accessed.
  • Follow CISA ICS recommended practices and defense-in-depth guidance to reduce exposure and improve monitoring around OT/ICS assets.
