Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the Vasion Print Application version
    Access the admin console or check the application's about/version information page. The version is typically displayed in the UI under Help > About or in the system information section.
    Affected if The Application version is below 20.0.1923
  2. Identify the Virtual Appliance Host version
    Access the virtual appliance management interface or check the appliance's system information. The version is typically displayed on the appliance dashboard or in the system settings.
    Affected if The Virtual Appliance Host version is below 22.0.843
  3. Verify if session authentication is in use
    Check if the Vasion Print application is configured to accept user logins. This vulnerability affects environments where user authentication is enabled.
    Affected if User authentication is enabled and either the Application version is below 20.0.1923 or the Virtual Appliance version is below 22.0.843

A user is affected if their Vasion Print Application version is below 20.0.1923 or their Virtual Appliance Host version is below 22.0.843, and user authentication is enabled.

Recommended fix High confidence

Virtual Appliance Host 22.0.843 / Application 20.0.1923 or later

  1. Backup the current Vasion Print/Virtual Appliance configuration and data
  2. Verify current version is below 20.0.1923 (Application) and/or below 22.0.843 (Virtual Appliance Host)
  3. Download the fixed release: Virtual Appliance Host 22.0.843 or later, Application 20.0.1923 or later from help.printerlogic.com or the official vendor portal
  4. Review upgrade prerequisites and compatibility notes in the official documentation
  5. Apply the upgrade following the vendor's standard upgrade procedure for Virtual Appliance deployments
  6. After upgrade, verify the new version meets the fixed releases (Application >= 20.0.1923, Virtual Appliance Host >= 22.0.843)
  7. Validate that the Session Fixation vulnerability is resolved by confirming session IDs are regenerated upon authentication
