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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity none, availability none.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Attack vector: Network — reachable from anywhere that can route to the service.
Attack complexity: Low — the attack works reliably, with no preparation.
Privileges required: None — an unauthenticated stranger can try it.
User interaction: None — nobody has to be tricked into anything.
Scope: Unchanged — the damage stays inside the vulnerable component.
Confidentiality impact: High — total loss, or loss the attacker controls.
Integrity impact: None.
Availability impact: None.
