itsourcecode Online Laundry Management System SQL Injection Vulnerability in Login Function

A SQL injection vulnerability has been identified in the Online Laundry Management System version 1.0. The issue arises in the login.php file, where the application fails to properly validate user input for the 'username' parameter. This lack of input sanitization allows attackers to inject malicious SQL queries, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information. The vulnerability can be exploited remotely without any authentication.

Impact

Exploitation of this vulnerability allows for SQL injection, which could lead to unauthorized database access, data leakage, data manipulation, and in some cases, execution of administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to the login.php file with a crafted 'username' 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 can also help mitigate such vulnerabilities.
