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 FlexNet Manager Suite version
    Check the installed version of FlexNet Manager Suite in the system information or about page. Common locations: Help > About in the web interface, or check the installation directory for version files.
    Affected if Version is FlexNet Manager Suite 2025 R1 (any minor update within this release)
  2. Locate read-only user accounts
    Navigate to the user management or account settings section in the FlexNet Manager Suite administrative interface. Identify accounts that are assigned read-only or restricted roles.
    Affected if Any user account exists with read-only or non-administrative role assignments
  3. Verify access control configuration for administrative functions
    Review the access control settings or permission matrix in the system configuration. Check which roles are permitted to access administrative functions such as user management, system settings, or role assignment features.
    Affected if Read-only roles are granted access to any administrative function or feature
  4. Test read-only user access to administrative interfaces
    Using a read-only user account, attempt to access administrative panels, modify user roles, or execute administrative actions. Check if the system enforces role restrictions or allows unauthorized privilege escalation.
    Affected if Read-only users can access or modify administrative settings or elevate their privileges

A user is affected if running FlexNet Manager Suite 2025 R1 and read-only accounts can access administrative functions due to improper access control enforcement.
