Code-Projects Real Estate Property Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Code-Projects Real Estate Property Management System version 1.0. The issue resides in the '/Admin/InsertCity.php' file, where the 'cmbState' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access, data manipulation, and potential service disruption.

Impact

Exploitation of this vulnerability allows for unauthorized access to the database, with the potential to leak, modify, or delete sensitive data. Additionally, it could lead to unauthorized control over the system or cause a disruption of service.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/Admin/InsertCity.php' with the 'cmbState' parameter. The injection payload can be crafted to exploit the SQL injection vulnerability, such as by using a time-based blind SQL injection payload that leverages the SQL 'SLEEP' function.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
