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.
-
Locate the Oretnom23 Blog Site installationSearch the web server filesystem for main.php files that contain 'user_add' function and are part of the Oretnom23 Blog Site application. Common paths include /var/www/html/, /www/, or C:\inetpub\wwwroot\.Affected if main.php containing the user_add function is found in a web-accessible directory.
-
Confirm the application versionCheck for a version file, readme, or the main.php header for version identifiers. The affected version is specifically 1.0.Affected if The installed version is Oretnom23 Blog Site 1.0.
-
Identify if the user_add function is accessibleDetermine if the application's user registration or user_add functionality is enabled and reachable via HTTP/HTTPS. Check if main.php is directly accessible or called through an entry point.Affected if The user_add function in main.php is accessible to unauthenticated or low-privilege users.
-
Check database for stored XSS payloadsQuery the users table in the database for any suspicious JavaScript tags (<script>), event handlers (onerror, onload, etc.), or encoded payloads in the name and email fields. Example SQL: SELECT name, email FROM tbl_users WHERE name LIKE '%<%' OR email LIKE '%<%';Affected if Records exist in the users table containing JavaScript code or HTML tags in the name or email fields.
-
Review server access logs for exploitation attemptsSearch web server access logs (Apache access.log, Nginx access.log) for POST requests to main.php with name/email parameters containing XSS patterns. Look for patterns like <script, javascript:, or event handlers.Affected if Log entries show malicious input patterns being submitted to the user_add function.
A user is affected if Oretnom23 Blog Site 1.0 is installed with the user_add function in main.php accessible, and the users table contains unsanitized JavaScript code in name or email fields.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement input validation and proper output encoding for the name and email parameters in the user_add function. Additionally, implement Content Security Policy (CSP) headers as a defense-in-depth measure.
