SourceCodester Hotel and Lodge Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in SourceCodester Hotel and Lodge Management System version 1.0. The issue resides in the file '/pages/save_room.php', where the 'floorno' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, 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 data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/pages/save_room.php' with the 'floorno' parameter. The request can include injected SQL code that exploits the vulnerability, taking advantage of the application's failure to properly validate user input before executing database queries.

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.
