CVE-2025-34195 — Vasion Virtual Appliance Application security vulnerability

Critical CVSS 9.8

Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 1.0.735 and Application prior to 20.0.1330 (Windows client deployments) contain a remote code execution vulnerability during driver installation caused by unquoted program paths. The PrinterInstallerClient driver-installation component launches programs using an unquoted path under "C:\Program Files (x86)\Printer Properties Pro\Printer Installer". Because the path is unquoted, the operating system may execute a program located at a short-path location such as C:\Program.exe before the intended binaries in the quoted path. If an attacker can place or cause a program to exist at that location, it will be executed with the privileges of the installer process (which may be elevated), enabling arbitrary code execution and potential privilege escalation. This weakness can be used to achieve remote code execution and full compromise of affected Windows endpoints. This vulnerability has been identified by the vendor as: V-2022-006 — Driver Upload Security.

Matched remediation archetype

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
