Campcodes Grocery Sales and Inventory System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Campcodes Grocery Sales and Inventory System version 1.0. The issue arises in the file '/ajax.php?action=delete_product', where insufficient input validation of the 'id' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database queries. This could lead to unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a POST request to '/ajax.php?action=delete_product' with a crafted 'id' parameter that includes a malicious SQL payload. The injection point is the 'id' parameter, which is not properly sanitized before being used in SQL queries. This vulnerability can be exploited using automated tools like sqlmap, which can be directed to target the specific injection point and extract database information.

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 mitigate such vulnerabilities.
