Overview

CVE-2025-34221 is a critical-severity vulnerability. It was published on September 29, 2025 and has a CVSS 3.1 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 25.2.169 and Application prior to version 25.2.1518 (VA/SaaS deployments) expose every internal Docker container to the network because firewall rules allow unrestricted traffic to the Docker bridge network. Because no authentication, ACL or client‑side identifier is required, the attacker can interact with any internal API, bypassing the product’s authentication mechanisms entirely. The result is unauthenticated remote access to internal services, allowing credential theft, configuration manipulation and potential remote code execution. This vulnerability has been identified by the vendor as: V-2025-002 — Authentication Bypass - Docker Instances.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
