Summary

CVE-2025-34195 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Vasion Virtual Appliance Application. Its CVSS base score is 8.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 43% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-3 (Malicious Code Protection) and CM-7 (Least Functionality) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Vasion Print, formerly known as PrinterLogic, is affected by CVE-2025-34195 in Virtual Appliance Host versions prior to 1.0.735 and Application versions prior to 20.0.1330 on Windows client deployments. The flaw is an unquoted service path in the PrinterInstallerClient driver-installation component, which launches executables from the path "C:\Program Files (x86)\Printer Properties Pro\Printer Installer". Because the path is unquoted, Windows may instead run a binary such as C:\Program.exe if it exists, and this occurs with the privileges of the installer process.

An attacker who can write to a short-path location on the system can place a malicious executable that will be executed during driver installation. This grants arbitrary code execution and potential privilege escalation, enabling full compromise of the affected Windows endpoint. The vulnerability is tracked by the vendor as V-2022-006 and is classified under CWE-434.

Vendor security bulletins at the provided PrinterLogic URLs describe the issue and direct customers to upgrade the Virtual Appliance Host to 1.0.735 or later and the Application to 20.0.1330 or later. The EPSS score remains low and unchanged at 0.0152 with no material increase after disclosure.

Vulnerability Data

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.

Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.

Least functionality restricts the file types and automatic processing capabilities the system will accept.

finds

Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.

prevents

Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.

prevents

Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.

mitigates

Application allow-listing and pre-use scanning of received files directly blocks the introduction of executable content that has not been vetted, eliminating the primary vector for unrestricted dangerous file uploads.
