CVE-2025-34189Public exploit

Local session hijacking via unauthenticated file-based IPC

Published Sep 19, 2025 · Updated Sep 19, 2025

Insecure IPC in Vasion Print Virtual Appliance Host before 1.0.735 and Application before 20.0.1330 allows local users to hijack sessions. The PrinterInstallerClient service accepts files from world-writable request directories beneath /opt/PrinterInstallerClient/tmp without authenticating their origin. Local users on affected macOS or Linux clients can read IPC data or submit crafted requests that privileged daemons execute in another session.
