itsourcecode Online Tour and Travel Management System SQL Injection Vulnerability in Currency Management

A critical SQL injection vulnerability has been identified in the Online Tour and Travel Management System version 1.0. The issue resides in the file '/admin/operations/currency.php', where the 'curr_code' parameter is not properly validated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database queries. This could lead to 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 '/admin/operations/currency.php' with a crafted 'curr_code' parameter that includes malicious SQL payloads. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to implement input validation and use prepared statements to prevent SQL injection. Regular security audits can also help identify and fix vulnerabilities.
