Print Virtual Appliance Host: Download of Code Without Integrity Check
CVE-2025-34212 is a critical-severity download of code without integrity check 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. The record lists version 22.0.843 as the first without the flaw, so updating Print Virtual Appliance Host to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.67% chance of exploitation within 30 days, higher than 53% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Print Virtual Appliance Host to 22.0.843 or a later version.
- Update Print Application to 20.0.1923 or a later version.
- Update Virtual Appliance Application to 20.0.1923 or a later version.
- 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 prior to version 22.0.843 and Application prior to version 20.0.1923 (VA/SaaS deployments) possess CI/CD weaknesses: the build pulls an unverified third-party image, downloads the VirtualBox Extension Pack over plain HTTP without signature validation, and grants the jenkins account NOPASSWD for mount/umount. Together these allow supply chain or man-in-the-middle compromise of the build pipeline, injection of malicious firmware, and remote code execution as root on the CI host. This vulnerability has been identified by the vendor as: V-2023-007 — Supply Chain Attack.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Download of Code Without Integrity Check
The product downloads source code or an executable from a remote location and executes the code without sufficiently verifying the origin and integrity of the code.
How developers prevent this class of flaw
- Perform proper forward and reverse DNS lookups to detect DNS spoofing.
- Encrypt the code with a reliable encryption scheme before transmitting.
- Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
