Print Virtual Appliance Host: Insufficiently Protected Credentials
CVE-2025-34196 is a critical-severity insufficiently protected credentials 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 25.1.102 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 0.48% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Print Virtual Appliance Host to 25.1.102 or a later version.
- Update Print Application to 25.1.1413 or a later version.
- Update Virtual Appliance Application to 25.1.1413 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 versions prior to 25.1.102 and Application prior to 25.1.1413 (Windows client deployments) contain a hardcoded private key for the PrinterLogic Certificate Authority (CA) and a hardcoded password in product configuration files. The Windows client ships the CA certificate and its associated private key (and other sensitive settings such as a configured password) directly in shipped configuration files (for example clientsettings.dat and defaults.ini). An attacker who obtains these files can impersonate the CA, sign arbitrary certificates trusted by the Windows client, intercept or decrypt TLS-protected communications, and otherwise perform man-in-the-middle or impersonation attacks against the product's network communications. This vulnerability has been identified by the vendor as: V-2022-001 — Configuration File Contains CA & Private Key.

The underlying weakness: Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
How developers prevent this class of flaw
- Use an appropriate security mechanism to protect the credentials.
- Make appropriate use of cryptography to protect the credentials.
- Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
