Campcodes School Fees Payment Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Campcodes School Fees Payment Management System version 1.0. The issue resides in the file '/ajax.php?action=save_student', where insufficient input validation of the 'id' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to access the database without authorization, manipulate or delete data, and retrieve sensitive information. Such actions could severely compromise the application's data integrity and overall security.

Reproduction

To reproduce this vulnerability, send a POST request to '/School_Fees_Payment_Management_System/ajax.php?action=save_student' with a crafted 'id' parameter that includes malicious SQL payloads. The absence of input validation on the 'id' parameter will allow the injected SQL to be executed, demonstrating the SQL injection vulnerability.

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 user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can further enhance the application's security.
