Code-Projects Simple Laundry System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Code-Projects Simple Laundry System version 1.0, specifically in the '/userchecklogin.php' file. This vulnerability arises from inadequate validation of the 'userid' parameter, allowing attackers to inject malicious SQL queries. The exploitation of this vulnerability can lead to unauthorized access to the database, manipulation or deletion of data, and exposure of sensitive information. Notably, this vulnerability can be exploited remotely without any authentication.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized data access, data modification or deletion, and potential execution of administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to the '/userchecklogin.php' file with a crafted 'userid' parameter that includes malicious SQL code. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

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 are also advisable.
