Code-Projects Feedback System SQL Injection Vulnerability in Checklogin.php

A SQL injection vulnerability has been identified in Code-Projects Feedback System version 1.0, specifically within the '/admin/checklogin.php' file. The vulnerability arises from inadequate input validation of the 'email' parameter, allowing attackers to inject malicious SQL queries. This exploitation can be performed remotely, without the need for authentication.

Impact

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

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/checklogin.php' with a crafted 'email' parameter that includes malicious SQL payloads. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, and minimize database user permissions.
