CVE-2009-5151

Missing Digital Signature

Published: May 11, 2018 | Last Updated: Sep 24, 2020

The stub component of Absolute Computrace Agent V70.785 executes code from a disk's inter-partition space without requiring a digital signature for that code, which allows attackers to execute code on the BIOS. This allows a privileged local user to achieve persistent control of BIOS behavior, independent of later disk changes.

What is the Absolute Agent (formerly Absolute Computrace Agent)?

The Absolute Computrace Agent is a piece of software that is packaged with Absolute's Persistence technology embedded in over 1 Billion devices. The agent provides for visibility and control of the device by creating a digital tether between the device, and the Absolute Monitoring Center.

How can I check the Absolute agent version deployed on my device?

Log into the Absolute console and go to Assets > Devices. In the report, go to the settings area and edit columns in the report to show the Agent column. This column will report on the version of the agent that is deployed to devices under Absolute management.

My Absolute Agent is reporting an older version - How can I update the Absolute Agent?

Absolute manages the agent upgrade process as part of our service. If your device is regularly calling into the Absolute Monitoring Center then the upgrade to our latest agent will happen automatically. If you are still seeing an outdate agent on a device under management, contact the Absolute support team for assistance.
