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_course', where insufficient validation of the 'id' parameter allows for the injection of malicious SQL queries. This vulnerability can be exploited remotely, potentially leading to unauthorized database access, data manipulation, and disruption of service.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to access, modify, or delete database information. This could include sensitive data, posing a significant risk to 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_course' with a crafted 'id' parameter that includes a SQL injection payload. The request can be made using tools like sqlmap, which can automate the exploitation of SQL injection vulnerabilities.

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 also help mitigate such vulnerabilities.
