This vulnerability has been confirmed as remediated by the vendor; however, the exact patch version or release date is not specified. Users should ensure they are running the latest versions of Vasion Print Application (at least version 25.1.102 for the Virtual Appliance Host and 25.1.1413 for macOS/Linux clients) or later.
Description
Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 25.1.102 and Application versions prior to 25.1.1413 (macOS/Linux client deployments) are vulnerable to an authentication bypass in PrinterInstallerClientService. The service requires root privileges for certain administrative operations, but these checks rely on calls to geteuid(). By preloading a malicious shared object overriding geteuid(), a local attacker can trick the service into believing it is running with root privileges. This bypass enables execution of administrative commands (e.g., enabling debug mode, managing configurations, or invoking privileged features) without proper authorization. While some actions requiring write access to protected files may still fail, the flaw effectively breaks the intended security model of the inter-process communication (IPC) system, allowing local attackers to escalate privileges and compromise system integrity. This vulnerability has been confirmed to be remediated, but it is unclear as to when the patch was introduced.
