Print Virtual Appliance Host: Reliance on IP Address for Authentication
CVE-2025-34202 is a high-severity reliance on IP address for authentication vulnerability in Print Virtual Appliance Host from Vasion, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. The record lists version 25.2.169 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 0.98% chance of exploitation within 30 days, higher than 63% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Print Virtual Appliance Host to 25.2.169 or a later version.
- Update Print Application to 25.2.1518 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.

Official description
Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to 25.2.169 and Application prior to 25.2.1518 (VA and SaaS deployments) expose Docker internal networks in a way that allows an attacker on the same external L2 segment — or an attacker able to add routes using the appliance as a gateway — to reach container IPs directly. This grants access to internal services (HTTP APIs, Redis, MySQL, etc.) that are intended to be isolated inside the container network. Many of those services are accessible without authentication or are vulnerable to known exploitation chains. As a result, compromise of a single reachable endpoint or basic network access can enable lateral movement, remote code execution, data exfiltration, and full system compromise. This vulnerability has been identified by the vendor as: V-2025-003 — Insecure Access to Docker Instance from WAN.

The underlying weakness: Reliance on IP Address for Authentication
The product uses an IP address for authentication.
How developers prevent this class of flaw
- Use other means of identity verification that cannot be simply spoofed. Possibilities include a username/password or certificate. While IP address verification can be a useful part of an authentication scheme, but it should not be the single factor required for authentication.
