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 Devolutions Server installation

    Affected if Devolutions Server is installed on the system
  2. Determine installed version number
    Check the version of Devolutions Server. This is typically visible in the application itself, in Windows Programs and Features, or in the installation directory's version info. Look for a version string like '2023.1.x.x' or similar.
    Affected if The installed version is 2023.1.5.0 or any version below 2023.1.6.0
  3. Verify support ticket feature is accessible
    Access the Devolutions Server web interface and navigate to the support or help section where support tickets can be submitted. Log in with any valid user account.
    Affected if The support ticket feature is available and accessible through the web interface
  4. Check for unauthorized endpoint access
    If you have access to server logs or can test web endpoints, look for or attempt to access support-related endpoints such as /api/support, /api/ticket, or similar diagnostic file download endpoints without proper admin authorization.
    Affected if Support ticket submission or diagnostic file download endpoints respond without requiring elevated privileges beyond basic authentication

The environment is affected if Devolutions Server version 2023.1.5.0 or below is installed and the support ticket feature is accessible to non-admin authenticated users.
