CVE-2025-34195Public exploit

Code execution via unquoted driver-installation path

Published Sep 19, 2025 · Updated Sep 19, 2025

Path hijacking in Vasion Print Application before 20.0.1330 and Virtual Appliance Host before 1.0.735 allows attackers to execute code. PrinterInstallerClient launches driver-installation programs from C:\Program Files (x86)\Printer Properties Pro\Printer Installer without quoting the path, so Windows resolves C:\Program.exe first. Exploitation requires an attacker to place C:\Program.exe on a Windows endpoint before a printer driver installation, after which it runs with the installer process's privileges.
