itsourcecode Gym Management System SQL Injection Vulnerability in view_member.php

A critical SQL injection vulnerability has been identified in the itsourcecode Gym Management System version 1.0. The issue resides in the file view_member.php, where the id parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, allowing attackers to gain unauthorized access to the database, leak sensitive data, tamper with information, and potentially disrupt services.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation of data, leakage of sensitive information, and could lead to a complete compromise of the system.

Reproduction

The vulnerability can be reproduced by sending a request to view_member.php with a crafted id parameter that includes SQL injection payloads. Various types of SQL injection techniques can be used, such as boolean-based blind, error-based, time-based blind, and UNION-based injections. Tools like sqlmap can automate the exploitation process and demonstrate the vulnerability.

Remediation

To address this vulnerability, 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 enhance overall security.
