Patching: Upgrade to a patched version above 1.0 if available. Check code-projects official repository or project page for security releases. NOTE: No specific patch version identified in provided data—vendor contact or security advisory required. Code-Level Mitigation: Replace all SQL string concatenation in /reservation/demo.php with prepared statements using parameterized queries (PHP mysqli_prepare() or PDO prepared statements). Example: Use $mysqli->prepare('SELECT * FROM reservations WHERE start_date = ?') with bound parameters instead of SELECT * FROM reservations WHERE start_date = ' . $_GET['Start'] . ' Input Validation: Implement strict whitelist validation on 'Start' parameter: validate date format (YYYY-MM-DD), range checks, and type enforcement before use in any query or output context. WAF/IDS Mitigation: Deploy Web Application Firewall (WAF) rules to block common SQL injection patterns in the Start parameter (e.g., detect single quotes, SQL keywords like UNION, OR, semicolons). This is a temporary measure pending patching. Access Control: Restrict access to /reservation/demo.php at network level if it is demo/development code that should not be production-facing. Consider moving to non-public testing environment.
