CVE-2024-4973Public exploitNetwork attack vector

Database access via injectable registration fields

Published May 16, 2024 · Updated Aug 1, 2024

SQL injection in Code Projects Simple Chat System in PHP 1.0 allows remote attackers to read or modify database data through registration. The registration flow sends the name, number, and address fields to add_user.php, where quote-bearing values alter a MySQL query and enable boolean- or time-based extraction. No account is required to submit the registration request, and successful exploitation exposes or changes data available to the application database account.
