CVE-2025-27644Public exploit

SYSTEM code execution via trusted temporary package files

Published Mar 5, 2025 · Updated Nov 3, 2025

Privilege escalation in Vasion Print Application before 20.0.2368 and Virtual Appliance Host before 22.0.933 lets local users run code as SYSTEM. The Windows client installs printer drivers as NT AUTHORITY\SYSTEM but blindly trusts temporary package files in the user-writable C:\Windows\Temp\data directory. A low-privileged local user can replace those files or redirect the directory with a junction during driver installation, causing attacker-controlled code to run as SYSTEM.
