itsourcecode Gym Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in the itsourcecode Gym Management System version 1.0. The issue resides in the file '/ajax.php?action=delete_user', where the 'id' parameter is manipulated, leading to unauthorized database access. This vulnerability allows attackers to inject malicious SQL queries, potentially modifying or deleting data and accessing sensitive information. The flaw can be exploited remotely without authentication.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could lead to 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?action=delete_user' with the 'id' parameter. The request can be made using tools like sqlmap, which can automate the exploitation of SQL injection vulnerabilities. For example, sqlmap can be used to extract database information by specifying the target URL and the 'id' parameter 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 can also help mitigate such vulnerabilities.
