Itsourcecode Online House Rental System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the Online House Rental System version 1.0, specifically within the manage_tenant.php file. This vulnerability arises from inadequate validation of the 'id' parameter, allowing remote attackers to inject malicious SQL queries. The exploitation of this vulnerability could lead to unauthorized access to the database, manipulation of data, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, which could be used to access, modify, or delete database information. Additionally, it could lead to unauthorized execution of commands on the server, depending on the application's database interaction.

Reproduction

The vulnerability can be reproduced by sending a GET request to the manage_tenant.php file with a crafted 'id' parameter. This can be done using a web browser or a tool like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to implement prepared statements and parameter binding to separate SQL code from user input. Additionally, input validation and filtering should be applied to ensure that data conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance the application's security.
