Campcodes Supplier Management System SQL Injection Vulnerability in Login Component

A SQL injection vulnerability has been identified in Campcodes Supplier Management System version 1.0. The issue resides in the Login component, specifically within the '/Supply_Management_System/index.php' file. The vulnerability is triggered by manipulating the 'txtUsername' parameter, allowing attackers to inject malicious SQL queries. This exploitation can be done remotely, without any authentication requirements.

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 services.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/Supply_Management_System/index.php' with the 'txtUsername' parameter. Injected SQL payloads can be used to exploit the vulnerability, such as boolean-based blind, error-based, or time-based blind SQL injection techniques.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. Input validation and filtering should be implemented to ensure user input conforms to expected formats. Additionally, minimize database user permissions and conduct regular security audits.
