CVE-2025-34193

SYSTEM escalation via unprotected legacy Windows clients

Published Sep 19, 2025 · Updated Sep 19, 2025

Local privilege escalation in Vasion Print before Host 25.1.102 or Application 25.1.1413 allows local users to gain SYSTEM access. PrinterInstallerClientInterface.exe, PrinterInstallerClient.exe, and PrinterInstallerClientLauncher.exe are 32-bit Windows binaries built without DEP, ASLR, CFG, or stack protection and include Pascal, Delphi, and Python 2 code. Exploitation requires a separate crafted input or exploit primitive; the record identifies none specific to this CVE.
