CVE-2025-34208: Vasion Print (formerly PrinterLogic) Insecure Password Hashing

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2025-10-02 · updated 2026-10-18
• Weakness: CWE-327

Description

Vasion Print (formerly PrinterLogic) Virtual Appliance Host and Application (VA/SaaS deployments) store user passwords using unsalted SHA-512 hashes with a fall-back to unsalted SHA-1. The hashing is performed via PHP's `hash()` function in multiple files (server_write_requests_users.php, update_database.php, legacy/Login.php, tests/Unit/Api/IdpControllerTest.php). No per-user salt is used and the fast hash algorithms are unsuitable for password storage. An attacker who obtains the password database can recover cleartext passwords via offline dictionary or rainbow table attacks. The vulnerable code also contains logic that migrates legacy SHA-1 hashes to SHA-512 on login, further exposing users still on the old hash. This vulnerability was partially resolved, but still present within the legacy authentication platform.
