Last modified

CVE-2025-34221 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 1.36% chance of exploitation in the next 30 days.
