Submit #648580: SourceCodester Online Student File Management System 1.0 SQL Injectioninfo

TitleSourceCodester Online Student File Management System 1.0 SQL Injection
DescriptionDuring the security review of the "Online Student File Management System", I discovered a critical SQL injection vulnerability within the file inclusion chain: /admin/index.php → /admin/login.php → /admin/login_query.php. Specifically, when users access /admin/index.php, it includes /admin/login.php to display the login form, and /admin/login.php subsequently includes /admin/login_query.php to handle the login logic. In line 9 of /admin/login_query.php, the username parameter is directly inserted into the SQL query: "SELECT * FROM user WHERE username = '$username' && password = '$password'" without any input validation or parameterized query implementation. This insecure coding practice allows attackers to inject malicious SQL code through the username parameter, potentially gaining unauthorized database access, modifying or deleting data, and accessing sensitive information. Immediate remedial measures are required to ensure system security and protect data integrity.
