Code-Projects Online Guitar Store SQL Injection Vulnerability in Login.php

A SQL injection vulnerability exists in the 'Online Guitar Store' project version 1.0, specifically within the 'login.php' file. The issue arises because the 'L_email' parameter can be manipulated to inject malicious SQL code. This unsanitized input is directly used in SQL queries, allowing attackers to alter the queries and execute unauthorized database operations. The vulnerability can be exploited remotely, without any authentication.

Impact

Exploitation of this vulnerability allows attackers to manipulate SQL queries, potentially leading to unauthorized data access, data modification, and in some cases, full control over the application or server.

Reproduction

The vulnerability can be reproduced by sending a POST request to 'login.php' with an injected payload in the 'L_email' parameter. This can be done using tools like sqlmap, which can automate the injection process and exploit the vulnerability.

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 that user input meets expected formats, and database user permissions should be minimized to reduce the impact of potential attacks.
