SourceCodester Open Source Clinic Management System SQL Injection Vulnerability in Login.php

A critical SQL injection vulnerability has been identified in SourceCodester Open Source Clinic Management System version 1.0. The issue resides in the login.php file, where the email parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, allowing attackers to gain unauthorized access to the database, modify or delete data, and access sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation of data, leakage of sensitive information, and potential disruption of services.

Reproduction

The vulnerability can be reproduced by sending a POST request to the login.php file with the email parameter. The request can include a crafted SQL payload that exploits the application's SQL query handling. This can be done using tools like sqlmap, which automates the process of finding and exploiting 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.
