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 arises in the file '/ajax.php?action=delete_fees', where insufficient validation of the 'id' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, leading to unauthorized database access, data manipulation, and potential leakage of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database queries. This could result in 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 '/School_Fees_Payment_Management_System/ajax.php?action=delete_fees' with an 'id' parameter that includes a crafted SQL payload. The injection can be verified by using a payload that, for example, extracts database information or demonstrates the injection's effectiveness through a boolean-based blind SQL injection technique.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection vulnerabilities. Additionally, input validation and filtering should be implemented to ensure that user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance the application's security.
