itsourcecode Free Hotel Reservation System SQL Injection Vulnerability in Login Component

A SQL injection vulnerability has been identified in the Free Hotel Reservation System by itsourcecode, specifically in version 1.0. The issue arises in the login.php file within the admin directory, where the email parameter is not properly validated. This lack of input sanitation 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, where attackers can interfere with the application's database queries. This could lead to unauthorized data access, data manipulation, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to /hotel/admin/login.php with an injected SQL payload in the email parameter. 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.
