PHPGurukul User Registration and Login System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in the PHPGurukul User Registration & Login and User Management System, specifically in version 3.3. The issue resides in the '/login.php' file, where the 'password' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access and potential data manipulation.

Impact

Exploitation of this vulnerability allows attackers to execute arbitrary SQL commands, potentially leading to unauthorized access to the database, manipulation or deletion of data, and access to sensitive information.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/login.php' with the 'password' parameter crafted to include SQL injection payloads. 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 to prevent SQL injection, validate and sanitize user inputs, and implement a web application firewall. Regularly updating the application and monitoring logs for suspicious activities can also help mitigate such vulnerabilities.
