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 checksWork through these to decide whether this CVE applies to you.
-
Determine installed DNN versionAccess the DNN site as host/admin, navigate to Host > About or use the Persona Bar menu to view the version information. Alternatively, check the VERSION.txt file in the website root directory if accessible.Affected if The installed version is below 9.13.8 (any version from original installation up to 9.13.7)
-
Verify public registration is enabledLog in as host or admin, go to Admin > Site Settings or Member Manager settings. Look for user registration settings - check if "Public" or "Verified" registration is allowed. This is typically found under Security Settings or Registration Settings.Affected if User registration is set to Public or Verified (allowing self-registration by anonymous users)
-
Confirm registration form is publicly accessibleOpen a browser in incognito/private mode and attempt to access the registration page (typically at /Registration or /Register or ?ctl=Register). Verify the form loads without requiring authentication.Affected if The registration form loads and accepts input without requiring login credentials
Your environment is affected if DNN version is below 9.13.8 AND the public registration feature is enabled and accessible to anonymous users.
