CVE-2025-34221
Vasion Virtual Appliance Host remote code execution
- Published29 Sept 2025
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.
