Variable querying in Privilege Management for Windows (PMfW)

Impacted Product:

Privilege Management for Windows (PMfW)


A medium severity vulnerability was discovered and verified in BeyondTrust’s Privilege Management for Windows (PMfW) whereby an attacker on a 32-bit machine could bypass application matching criteria. PMfW would match against user-level environment variables when checking application matching criteria. This could allow a malicious actor to bypass some application definitions by specifying their own environment variables.


PMfW default behavior was changed to check against system-level environment variables by default. This change was introduced in version 5.6SR2 of Privilege Management for Windows. BeyondTrust recommends customers upgrade to the latest version of PMfW as soon as possible.

Product Version
Privilege Management for Windows (PMfW) Prior to 5.6 SR2
Product Version
Privilege Management for Windows (PMfW) 5.6 SR2 and above

BeyondTrust would like to acknowledge Lockheed Martin Red team for reporting this issue.
