Code-Projects Student Enrollment System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in the Code-Projects Student Enrollment System version 1.0, specifically within the login.php file. This vulnerability arises from inadequate validation of user input in the 'username' parameter, allowing attackers to inject malicious SQL queries. Exploitation of this vulnerability could lead to unauthorized access to the database, manipulation or deletion of data, and exposure of sensitive information. Notably, this vulnerability can be exploited remotely without requiring any login or authorization.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized database access, leakage or modification of sensitive data, and potential disruption of services.

Reproduction

The vulnerability can be reproduced by sending a POST request to the login.php file with a crafted 'username' parameter that includes malicious SQL code. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance overall system security.
