    Affected if The installed version is exactly 4.0-24
  2. Verify version against CVE scope
    Compare the identified version number to the affected version range. This CVE affects only version 4.0-24, no other versions are listed as affected.
    Affected if The version is exactly 4.0-24 and no vendor patch has been applied
  3. Check for unauthorized access indicators
