Problem Description

A security update has been issued for Trend Micro DataArmor which resolves a privately disclosed, local vulnerability.  This vulnerability in the DataArmor pre boot could allow an attacker with local access to the laptop the ability to escalate privileges of an existing user account with established credentials on the device. Once user privileges are escalated the user could then potentially gain access to the DataArmor Recovery Console.

As the pre boot operating system of DriveArmor is very similar to DataArmor we verified that this potential vulnerability is present in DriveArmor as well and implemented a similar fix. 


Products Affected:
All versions of DataArmor and DriveArmor


Background and Impact:
Successful exploitation of this vulnerability could allow an attacker to modify limited cached data related to user authentication and gain access to the DataArmor recovery console.
