Campcodes Supplier Management System SQL Injection Vulnerability in Product Edit Function

A SQL injection vulnerability has been identified in Campcodes Supplier Management System version 1.0. The issue resides in the file '/manufacturer/edit_product.php', where the 'cmbProductUnit' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without the need for authentication.

Impact

Exploitation of this vulnerability allows unauthorized access to the database, where attackers can read, modify, or delete data. It also poses a risk of executing administrative operations on the database, potentially leading to a complete compromise of the application.

Reproduction

To reproduce this vulnerability, send a POST request to '/Supply_Management_System/manufacturer/edit_product.php' with the 'cmbProductUnit' parameter included. Inject a crafted SQL payload that exploits the application's SQL query handling. The injection can be verified by observing the application's response or by using a tool like sqlmap to automate the exploitation process.

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 user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance the application's security.
