Code-Projects Courier Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Code-Projects Courier Management System version 1.0. The issue resides in the file '/courier/edit-courier.php', where the 'OfficeName' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication requirements.

Impact

Exploitation of this vulnerability allows unauthorized database access, manipulation of data, and potential leakage of sensitive information. It poses a significant threat to the application's data integrity and overall security.

Reproduction

To reproduce this vulnerability, send a POST request to '/courier/edit-courier.php' with the 'OfficeName' parameter containing the injected SQL payload. The injection can be crafted to exploit boolean-based blind, error-based, or time-based blind SQL injection techniques. No authentication is required to access the vulnerable endpoint.

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.
