PHP EUVD-2025-18809

Immediate actions: (1) Apply input validation: Implement strict whitelist validation for the ID parameter (numeric-only if ID is an integer); (2) Use prepared statements: Replace all dynamic SQL with parameterized queries using mysqli_prepare() or PDO prepared statements with bound parameters; (3) Code example (PHP/PDO): $stmt = $pdo->prepare('SELECT * FROM students WHERE id = ?'); $stmt->execute([$_GET['ID']]); instead of SELECT * FROM students WHERE id = . $_GET['ID']; (4) WAF/IDS rules: Deploy Web Application Firewall rules to block SQL injection patterns (quotes, SQL keywords, comment syntax) in the ID parameter; (5) Principle of least privilege: Ensure database user credentials for the application have minimal necessary permissions (SELECT only on student records, no DROP/ALTER); (6) Check for vendor patches: Contact code-projects or review their repository for security updates—if no patch exists, consider migration to maintained alternatives (e.g., open-source school management systems with active security patching). No official CVE patch link is provided; remediation requires manual code review and patching by the deploying organization.
