What is CVE-2020-12612?
CVE-2020-12612 is a high-severity vulnerability in n/a, published on 12 Dec 2023. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
