SourceCodester Simple E-Commerce Bookstore SQL Injection Vulnerability

A SQL injection vulnerability has been identified in SourceCodester Simple E-Commerce Bookstore version 1.0. The issue resides in the 'index.php' file, where the 'login_username' 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, with the potential to access, modify, or delete database information. Such actions could disrupt service and compromise system security.

Reproduction

To reproduce this vulnerability, send a POST request to 'index.php' with the 'login_username' parameter set to include a SQL injection payload, such as 'admin' OR '1'='1'. The 'login_password' parameter can be filled with any value. This injection takes advantage of the application's SQL query handling, bypassing authentication mechanisms.

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 further enhance application security.
