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 NetCat CMS version
    Locate the version file or admin panel that displays the NetCat CMS installation version. Common locations include a 'version' file in the system directory, the admin dashboard 'About' section, or the installer manifest.
    Affected if The installed version is lower than 6.4.0.24248 (e.g., 6.4.0.24200 or earlier).
  2. Confirm CMS core is active
    Verify that the core NetCat CMS system is installed and operational on the server. Check that the main CMS files and database are accessible and the site loads properly.
    Affected if The CMS core is running and the version cannot be determined or is confirmed below 6.4.0.24248.
  3. Review accessible URL paths
    Identify which public-facing paths on the NetCat site are reachable without authentication. Common paths include the homepage, content pages, search functionality, and user-submitted form endpoints.
    Affected if Unauthenticated or low-privileged users can access CMS paths where user input is reflected in responses without sanitization.

If the NetCat CMS installation is confirmed to be version 6.4.0.24248 or lower, the environment is likely affected by this XSS vulnerability.
