itsourcecode Online Tour and Travel Management System SQL Injection Vulnerability in Disapprove User Functionality

A SQL injection vulnerability has been identified in the Online Tour and Travel Management System by itsourcecode, specifically in version 1.0. The issue arises in the admin/disapprove_user.php file, where the 'id' 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, which could be used to access, modify, or delete database information. Additionally, such vulnerabilities can sometimes be leveraged to execute administrative operations on the database or, in certain configurations, to execute commands on the server operating system.

Reproduction

The vulnerability can be reproduced by sending a crafted HTTP request to the admin/disapprove_user.php file with a manipulated 'id' parameter. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities. The injection can be performed using various techniques, such as boolean-based blind injection, error-based injection, stacked queries, or time-based blind injection, depending on the SQL server version and configuration.

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 security.
