What is CVE-2025-34194?

The Vasion Print application, including its Virtual Appliance Host and Windows client deployments, suffers from an insecure temporary-file handling vulnerability. This flaw allows local users to manipulate filenames or create symbolic links in the user directory, leading the PrinterInstallerClient components to write files with SYSTEM privileges. This escalation can compromise system confidentiality, integrity, and availability by enabling unauthorized modifications or replacements of critical files. While a fix is available, the range of affected versions is not yet fully established.
