AI-suggested
Organizations should immediately audit their deployments of Vasion Print Virtual Appliance Host and Application to identify affected versions. They must prioritize upgrading or patching to versions that eliminate the use of unsalted SHA-512 and SHA-1 hashes for password storage. If patches are unavailable, organizations should implement compensating controls such as enforcing password resets for all users and migrating to a secure password hashing scheme using modern algorithms like bcrypt, scrypt, or Argon2 with unique per-user salts and appropriate work factors. Review and refactor legacy authentication code to remove fallback to SHA-1 and ensure all password hashes are salted and slow-hashed. Limit access to password databases and logs to reduce the risk of data exfiltration. Monitor for unusual access patterns or authentication anomalies that may indicate exploitation attempts. Additionally, implement network segmentation and strict access controls around printing infrastructure to contain potential breaches. Conduct user awareness training to discourage password reuse across systems. Finally, maintain an incident response plan tailored to credential compromise scenarios.
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.
