CVE-2025-34223

Vasion Virtual Appliance Host authentication bypass

9.8 CRITICALPublic exploitEPSS 1.23%
  1. Published29 Sept 2025

Description

Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 22.0.1049 and Application prior to version 20.0.2786 (VA/SaaS deployments) contain a default admin account and an installation‑time endpoint at `/admin/query/update_database.php` that can be accessed without authentication. An attacker who can reach the installation web interface can POST arbitrary `root_user` and `root_password` values, causing the script to replace the default admin credentials with attacker‑controlled ones. The script also contains hard‑coded SHA‑512 and SHA‑1 hashes of the default password, allowing the attacker to bypass password‑policy validation. As a result, an unauthenticated remote attacker can obtain full administrative control of the system during the initial setup. This vulnerability has been identified by the vendor as: V-2024-022 — Insecure Installation Credentials.
