Campcodes Sales and Inventory System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Campcodes Sales and Inventory System version 1.0. The issue resides in the '/pages/supplier_add.php' file, where the 'name' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized access to the database, manipulation or deletion of data, and access to sensitive information. Such actions pose a significant risk to system security and data integrity.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/pages/supplier_add.php' with the 'name' parameter crafted to include a malicious SQL payload. This injection takes advantage of the application's failure to properly validate and sanitize user input, particularly in the 'name' parameter, which is used in SQL queries without adequate protection.

Remediation

To address this vulnerability, it is recommended to implement prepared statements and parameter binding to separate SQL code from user input, ensuring that injected data is not executed as part of a SQL command. Additionally, input validation and filtering should be applied to confirm that user data meets expected formats before processing. Minimizing database user permissions and conducting regular security audits can further enhance the application's security posture.
