Campcodes Sales and Inventory System SQL Injection Vulnerability in Stockin Add Page

A critical SQL injection vulnerability has been identified in Campcodes Sales and Inventory System version 1.0. The issue resides in the '/pages/stockin_add.php' file, where the 'prod_name' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, allowing attackers to gain unauthorized access to the database, leak sensitive information, modify or delete data, and potentially disrupt services.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation of data, leakage of sensitive information, and could lead to a complete compromise of the system.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/pages/stockin_add.php' with the 'prod_name' parameter. The request can include payloads that exploit the SQL injection, such as boolean-based blind injection or error-based injection. 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 the overall security of the application.
