Summary

CVE-2025-34208 is a high-severity Use of a Broken or Risky Cryptographic Algorithm (CWE-327) vulnerability in Vasion Virtual Appliance Application. Its CVSS base score is 8.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Password Cracking (T1110.002); ranked at the 34th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to IA-5 (Authenticator Management) and SA-11 (Developer Testing and Evaluation) — see the control section below for these in your framework.

Vulnerability Data

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…

more

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.

Mitigating Controls (NIST 800-53 r5) AI

SC-13 requires selection and implementation of specific cryptography types, directly stopping use of broken algorithms.

Authenticator management requires secure credential storage practices that include salted hashes.

Developer testing and evaluation can identify missing salt values through code review or analysis.

Development standards and tools can mandate salted hashing as part of secure implementation requirements.

prevents

Secure SDLC practices mandate correct password storage with salts, eliminating this exact weakness.

PR.DS-01 mostly match
prevents

Proper cryptographic hashing for data-at-rest protection directly requires salted hashes for passwords.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Mandating approved algorithms, cipher strength and usage standards directly stops the selection of broken or weak cryptographic primitives that attackers can exploit.

finds

Security testing can detect unsalted hashes but does not prevent their introduction.

prevents

The explicit call-out of cryptography-related legal constraints (import/export, key escrow, digital-signature validity) reduces the likelihood that an organization will adopt broken or non-compliant cryptographic algorithms that violate those rules.

prevents

Access to current specialist guidance and early vulnerability alerts enables timely replacement of broken or risky cryptographic algorithms with stronger alternatives.

prevents

Secure SDLC processes can include password-handling rules but do not guarantee salted hashes.

prevents

Application security requirements can mandate salted hashing but do not prescribe the technical detail.
