Code-Projects Student File Management System SQL Injection Vulnerability

A SQL injection vulnerability exists in Code-Projects Student File Management System version 1.0, specifically within the admin/login_query.php file. The vulnerability arises because the application improperly sanitizes the 'username' parameter, allowing attackers to inject malicious SQL code. This exploitation can be done remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and disruption of services.

Impact

Exploitation of this vulnerability allows for SQL injection, where an attacker can manipulate database queries. This could lead to unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a POST request to the admin/login_query.php file with a crafted 'username' parameter that includes SQL injection payloads. The application will process the injected SQL code, allowing access to the database or manipulation of data.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure that user input meets expected formats, blocking malicious data. Finally, database user permissions should be minimized, ensuring that accounts used for database connections have only the necessary privileges.
