CVE-2025-34218: CWE-306 Missing Authentication for Critical Function in Vasion Print Virtual Appliance Host
Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 22.0.1049 and Application prior to version 20.0.2786 (VA/SaaS deployments) expose internal Docker containers through the gw Docker instance. The gateway publishes a /meta endpoint which lists every micro‑service container together with version information. These containers are reachable directly over HTTP/HTTPS without any access‑control list (ACL), authentication or rate‑limiting. Consequently, any attacker on the LAN or the Internet can enumerate all internal services and their versions, interact with the exposed APIs of each microservice as an unauthenticated user, or issue malicious requests that may lead to information disclosure, privilege escalation within the container, or denial‑of‑service of the entire appliance. The root cause is the absence of authentication and network‑level restrictions on the API‑gateway’s proxy to internal Docker containers, effectively turning the internal service mesh into a public attack surface. This vulnerability has been identified by the vendor as: V-2024-030 — Exposed Internal Docker Instance (LAN).
AI Analysis
Technical Summary
Vasion Print Virtual Appliance Host and Application expose internal Docker containers via an unauthenticated API gateway proxy. The gateway publishes a /meta endpoint listing all microservice containers and their versions, which are accessible over HTTP/HTTPS without any access control, authentication, or rate limiting. This lack of authentication (CWE-306) enables attackers on the LAN or Internet to enumerate services, interact with microservice APIs unauthenticated, and potentially exploit these to cause information disclosure, privilege escalation within containers, or denial-of-service of the appliance. The vulnerability affects versions prior to 22.0.1049 (Host) and 20.0.2786 (Application) and has been assigned CVE-2025-34218 with a critical CVSS 4.0 score of 10.0.
Potential Impact
An attacker can enumerate all internal microservice containers and their versions, interact with exposed APIs without authentication, and potentially cause information disclosure, privilege escalation within containers, or denial-of-service of the entire appliance. This significantly compromises the confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor the vendor's advisories for updates. Until a fix is available, restricting network access to the appliance and isolating it from untrusted networks may reduce exposure.
