CVE-2025-34201 — Vasion Print (formerly PrinterLogic) Lack of Network Segmentation Between Docker Instances

Vasion Print (formerly PrinterLogic) Virtual Appliance Host and Application (VA and SaaS deployments) run many Docker containers on shared internal networks without firewalling or segmentation between instances. A compromise of any single container allows direct access to internal services (HTTP, Redis, MySQL, etc.) on the overlay network. From a compromised container, an attacker can reach and exploit other services, enabling lateral movement, data theft, and system-wide compromise.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.3% (30-day exploitation probability)+3
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Vasion Virtual Appliance Application, Vasion Virtual Appliance Host).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes, errors and authentication anomalies.

Affected scope

What should defenders know first?

CVE-2025-34201 is "Vasion Print (formerly PrinterLogic) Lack of Network Segmentation Between Docker Instances", rated High. It affects Virtual Appliance Application (Vasion); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.8 describes technical severity. EPSS 0.30% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
