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 file '/members/offering.php', where the 'trcode' 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, enabling attackers to leak, modify, or delete data. Additionally, it could lead to complete control over the system and disruption of services.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/members/offering.php' with the 'trcode' parameter. The injection can be crafted using various payloads, such as boolean-based blind, error-based, or time-based blind SQL injection techniques.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Input validation and filtering should be implemented to ensure that user input meets expected formats, blocking malicious data. Additionally, database user permissions should be minimized, granting only the necessary rights for operations.
