CVE-2025-34208 is a high-severity vulnerability affecting the Vasion Print Virtual Appliance Host and Application, including VA/SaaS deployments. The core issue lies in the insecure storage of user passwords using unsalted cryptographic hashes. Specifically, the product uses unsalted SHA-512 hashes with a fallback to unsalted SHA-1 for password hashing. These hashes are generated using PHP's `hash()` function in multiple source files, including server_write_requests_users.php, update_database.php, legacy/Login.php, and tests/Unit/Api/IdpControllerTest.php. The absence of per-user salts and the use of fast hash functions unsuitable for password storage (SHA-1 and SHA-512 without key stretching) make the password database vulnerable to offline dictionary and rainbow table attacks. An attacker who gains access to the password database can efficiently recover cleartext passwords. Furthermore, the vulnerable code includes logic that migrates legacy SHA-1 hashes to SHA-512 upon user login, which inadvertently exposes users still relying on the weaker SHA-1 hashes. Although partial remediation has been attempted, the legacy authentication platform remains vulnerable. This vulnerability is categorized under CWE-327 (Use of a Broken or Risky Cryptographic Algorithm) and CWE-759 (Use of a One-Way Hash without a Salt). The CVSS v4.0 score is 8.2 (high), reflecting the network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality. No known exploits are currently reported in the wild, but the weakness in password storage is a critical risk if the password database is compromised.

For European organizations using Vasion Print Virtual Appliance Host, this vulnerability poses a significant risk to user credential confidentiality. If an attacker obtains the password database—through a separate breach or insider threat—they can recover user passwords offline with relative ease due to the unsalted and fast hash algorithms. This can lead to credential compromise, unauthorized access to printing infrastructure, and potentially lateral movement within the network if credentials are reused. Given that printing systems often integrate with enterprise authentication and document workflows, compromise could lead to data leakage, disruption of printing services, and exposure of sensitive documents. The fallback to SHA-1 and the migration logic increase the attack surface by exposing legacy hashes. European organizations with compliance obligations under GDPR must consider the risk of personal data exposure and the potential regulatory consequences of credential leaks. The vulnerability's network-exploitable nature and lack of required privileges or user interaction increase the likelihood of exploitation once the password database is accessed. Although no exploits are known in the wild, the vulnerability's characteristics warrant urgent attention to prevent escalation.

1. Immediate mitigation should include isolating and securing the password database to prevent unauthorized access. 2. Organizations should enforce strong access controls and monitoring on the Vasion Print Virtual Appliance Host environment to detect and prevent breaches. 3. Vasion should be engaged to provide or prioritize a patch that replaces the current password hashing scheme with a modern, slow, salted password hashing algorithm such as Argon2, bcrypt, or PBKDF2 with unique per-user salts. 4. Until a patch is available, organizations should consider implementing compensating controls such as multi-factor authentication (MFA) for all users accessing the printing platform to reduce the risk of credential misuse. 5. Conduct a thorough audit of user credentials stored in the system and enforce password resets, especially for accounts that may still be using legacy SHA-1 hashes. 6. Monitor logs for suspicious login activity that could indicate attempts to exploit the migration logic. 7. Educate users and administrators about the risks of password reuse and encourage use of unique, strong passwords. 8. If feasible, segregate the printing infrastructure network segment to limit lateral movement in case of compromise. 9. Regularly review and update incident response plans to include scenarios involving credential database compromise.
