Detailsinfo

A vulnerability, which was classified as critical, has been found in BeyondTrust Privilege Management up to 5.6 on Windows. Affected by this issue is an unknown functionality of the component Environment Variable Handler. Impacted is confidentiality, integrity, and availability. CVE summarizes:

An issue was discovered in BeyondTrust Privilege Management for Windows through 5.6. When specifying a program to elevate, it can typically be found within the Program Files (x86) folder and therefore uses the %ProgramFiles(x86)% environment variable. However, when this same policy gets pushed to a 32bit machine, this environment variable does not exist. Therefore, since the standard user can create a user level environment variable, they can repoint this variable to any folder the user has full control of. Then, the folder structure can be created in such a way that a rule matches and arbitrary code runs elevated.
