Code-Projects Online Hotel Booking SQL Injection Vulnerability in Registration Management

A critical SQL injection vulnerability has been identified in the code-projects Online Hotel Booking application, version 1.0. The issue resides in the '/admin/registration.php' file, where the 'uname' 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, enabling attackers to manipulate database queries. This could result in unauthorized access to database information, modification or deletion of data, and in some cases, execution of administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/registration.php' with a crafted 'uname' parameter that includes malicious SQL code. This injection can be tested using SQL injection tools like sqlmap, which can automate the exploitation process and demonstrate the vulnerability by extracting database information.

Remediation

To address this vulnerability, it is recommended to implement prepared statements and parameter binding to prevent SQL injection. Additionally, user input should be validated and filtered to ensure it meets expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance overall application security.
