Print Virtual Appliance Host: Use of Hard-coded Cryptographic Key
CVE-2025-34217 is a critical-severity use of hard-coded cryptographic key vulnerability in Print Virtual Appliance Host from Vasion, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. There is no confirmed exploitation so far. EPSS estimates a 0.75% chance of exploitation within 30 days, higher than 55% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of Print Virtual Appliance Host you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on help.printerlogic.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Vasion Print (formerly PrinterLogic) Virtual Appliance Host and Application (VA/SaaS deployments) contain an undocumented 'printerlogic' user with a hardcoded SSH public key in '~/.ssh/authorized_keys' and a sudoers rule granting the printerlogic_ssh group 'NOPASSWD: ALL'. Possession of the matching private key gives an attacker root access to the appliance.
