What is CVE-2025-34190?
The Vasion Print Virtual Appliance Host and macOS/Linux client deployments are exposed to an authentication bypass through the PrinterInstallerClientService. Attackers can exploit this vulnerability by preloading a malicious shared object that overrides the geteuid() function, allowing them to gain unauthorized root privileges. This could lead to execution of administrative commands without proper authorization, thereby compromising system integrity. Despite certain operations requiring write access potentially failing, the bypass undermines the security of the inter-process communication system. Although the vulnerability has been addressed, specific affected version details are yet to be confirmed by Vasion.
