Code-Projects Real Estate Property Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in version 1.0 of the Code-Projects Real Estate Property Management System. The issue resides in the '/Admin/Property.php' file, where the 'cmbCat' 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, enabling attackers to manipulate database queries. This could result in unauthorized data access, data leakage, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/Admin/Property.php' with the 'cmbCat' parameter. The injection can be verified by using payloads that exploit boolean-based blind SQL injection or time-based blind SQL injection, such as injecting a condition that is always true or using the SQL 'SLEEP' function to create a delay.

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.
