Itsourcecode Employee Management System SQL Injection Vulnerability in Admin Login

A critical SQL injection vulnerability has been identified in the Itsoucecode Employee Management System version 1.0. The issue resides in the admin backend login interface, specifically within the 'index.php' file. The vulnerability allows remote attackers to manipulate the 'username' parameter, exploiting unfiltered input that is directly applied to SQL queries. This lack of proper input validation enables the execution of unauthorized SQL commands, potentially leading to unauthorized access, data manipulation, and exploitation of the underlying database.

Impact

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

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/index.php' with the 'username' parameter set to 'admin' and the 'Password' parameter crafted to exploit the SQL injection, such as using 'or 1=1 #'. This request can be made using tools like SQLMap, which can automate the exploitation of SQL injection vulnerabilities.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
