itsourcecode Agri-Trading Online Shopping System SQL Injection Vulnerability in Supplier Controller

A critical SQL injection vulnerability has been identified in the itsourcecode Agri-Trading Online Shopping System, specifically in version 1.0. The issue resides in the admin/suppliercontroller.php file, where the supplier parameter is manipulated, leading to unauthorized database access. This vulnerability can be exploited remotely, without authentication, due to inadequate input validation on the supplier parameter, allowing attackers to inject malicious SQL queries that could be used to access, modify, or delete database information.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can inject malicious SQL queries that the database will execute. This could lead to unauthorized data access, data manipulation, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to the admin/suppliercontroller.php file with the supplier parameter. The request can include crafted SQL payloads that exploit the injection vulnerability. This can be done using tools like sqlmap, which automates the process of finding and exploiting 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 that user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help mitigate such vulnerabilities.
