Local elevation to SYSTEM privileges
Published Jan 11, 2022 · Updated Jan 2, 2025
Elevation of privilege in Microsoft Windows Installer allows local users with low privileges to gain SYSTEM-level access on affected Windows builds. Microsoft has not published the vulnerable code path or the incorrect operation Windows Installer performs on attacker-controlled input. Exploitation requires local low-privileged access; successful exploitation grants control at the highest local privilege level.
