CVE-2025-27685Public exploitNetwork attack vector

CA private-key disclosure via embedded configuration

Published Mar 5, 2025 · Updated Nov 3, 2025

Key exposure in Vasion Print before Virtual Appliance Host 1.0.735 and Application 20.0.1330 allows remote attackers to obtain its CA private key. The clientsettings.dat XML file stores the PrinterInstaller CA certificate beside its matching unencrypted private key instead of protecting the secret separately. Unauthenticated network access is sufficient; possession of the reusable key permits interception of traffic that trusts the embedded authority, with no reported integrity or availability impact.
