HIGH-LEIT V05.08.01.03 and HIGH-LEIT V04.25.00.00 to 4.25.01.01 for Windows from Vivavis contain an insecure file and folder permissions vulnerability in prunsrv.exe. A regular user (non-admin) can exploit the weak folder and file permissions to escalate privileges and execute arbitrary code in the context of NT AUTHORITY\SYSTEM.
