Print Virtual Appliance Host: Use of a Broken or Risky Cryptographic Algorithm
CVE-2025-34208 is a high-severity use of a broken or risky cryptographic algorithm vulnerability in Print Virtual Appliance Host from Vasion, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. There is no confirmed exploitation so far. EPSS estimates a 0.44% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of Print Virtual Appliance Host you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on help.printerlogic.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official 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.

The underlying weakness: Use of a Broken or Risky Cryptographic Algorithm
The product uses a broken or risky cryptographic algorithm or protocol.
How developers prevent this class of flaw
- Ensure that the design allows one cryptographic algorithm to be replaced with another in the next generation or version. Where possible, use wrappers to make the interfaces uniform. This will make it easier to upgrade to stronger algorithms. With hardware, design the product at the Intellectual Property (IP) level so that one cryptographic algorithm can be replaced with another in the next generation of the hardware product.
- Carefully manage and protect cryptographic keys (see CWE-320). If the keys can be guessed or stolen, then the strength of the cryptography itself is irrelevant.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Industry-standard implementations will save development time and may be more likely to avoid errors that can occur during implementation of cryptographic algorithms. Consider the ESAPI Encryption feature.
