Itsourcecode Farm Management System SQL Injection Vulnerability in add-pig.php

A critical SQL injection vulnerability has been identified in the Itsourcecode Farm Management System version 1.0. The issue resides in the add-pig.php file, where the pigno parameter is manipulated to inject malicious SQL queries. This vulnerability allows remote attackers to interfere with database operations, potentially leading to unauthorized data access, data manipulation, and in some cases, executing arbitrary code on the server.

Impact

Exploitation of this vulnerability allows attackers to execute arbitrary SQL commands, appended to the original SQL query of the vulnerable endpoint. This could lead to unauthorized data access, data modification or deletion, and in some cases, executing arbitrary code on the server.

Reproduction

The vulnerability can be reproduced by sending a POST request to the add-pig.php file with a crafted pigno parameter that includes malicious SQL payloads. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. 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 can also help enhance overall system security.
