itsourcecode Gym Management System SQL Injection Vulnerability in ajax.php?action=delete_package

A critical SQL injection vulnerability has been identified in the itsourcecode Gym Management System version 1.0. The issue arises in the file ajax.php, specifically within the delete_package action. The vulnerability is caused by inadequate validation of the 'id' parameter, allowing attackers to inject malicious SQL queries. This exploitation can be performed remotely and without 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 result in unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a POST request to ajax.php with the action parameter set to delete_package. Include a crafted 'id' parameter that exploits the SQL injection vulnerability, such as one that uses a boolean-based blind SQL injection payload.

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 are also advisable.
