Code-Projects Simple Laundry System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Code-Projects Simple Laundry System version 1.0. The issue resides in the '/userfinishregister.php' file within the Parameter Handler component. The vulnerability is triggered by manipulating the 'firstName' parameter, allowing attackers to inject malicious SQL queries. This injection can be exploited remotely, without any authentication requirements, 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 potentially allow attackers to gain control over the application or its underlying system.

Reproduction

The vulnerability can be reproduced by sending a POST request to the '/userfinishregister.php' file with a crafted 'firstName' parameter that includes malicious SQL code. This payload can be designed to exploit time-based blind SQL injection techniques, such as using the SQL 'SLEEP' function to demonstrate the injection's effectiveness.

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.
