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=login', where the 'username' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication.

Impact

Exploitation of this vulnerability allows unauthorized access to the database, where attackers can leak, modify, or delete data. Additionally, it could lead to unauthorized control over the system or cause a disruption of service.

Reproduction

To reproduce this vulnerability, send a POST request to '/School_Fees_Payment_Management_System/ajax.php?action=login' with a crafted 'username' parameter that includes malicious SQL payloads. The injection can be verified by using a payload that, for example, delays the response by several seconds, indicating successful exploitation.

Remediation

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 are also advisable.
