Code-Projects Church Donation System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Code-Projects Church Donation System version 1.0. The issue resides in the '/members/search.php' file, where the 'username' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, allowing attackers to access, modify, or delete database information.

Impact

Exploitation of this vulnerability allows for unauthorized database access via the 'username' parameter, enabling attackers to manipulate database contents and potentially disrupt application services.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/members/search.php' with a crafted 'username' parameter that includes SQL injection payloads. The injected SQL code is executed by the application, exploiting the vulnerability.

Remediation

It is recommended to implement prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be applied to ensure user input meets expected formats, blocking malicious data. Minimizing database user permissions can also help reduce the impact of such vulnerabilities.
