Campcodes Supplier Management System SQL Injection Vulnerability in Admin Add Retailer PHP File

A SQL injection vulnerability has been identified in Campcodes Supplier Management System version 1.0. The issue resides in the admin/add_retailer.php file, where the cmbAreaCode parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, which could lead to unauthorized database access, manipulation or deletion of data, and exposure of sensitive information.

Reproduction

To reproduce this vulnerability, send a POST request to the admin/add_retailer.php file with the cmbAreaCode parameter. 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 mitigate such vulnerabilities.
