PHPGurukul News Portal SQL Injection Vulnerability in Login Component

A critical SQL injection vulnerability has been identified in PHPGurukul News Portal version 4.1. The issue resides in the login component, specifically within the '/admin/index.php' file. The vulnerability allows remote attackers to inject malicious SQL queries through the 'username' parameter. This unsanitized input is directly used in SQL queries, enabling unauthorized database access, data manipulation, and potential system compromise.

Impact

Exploitation of this vulnerability allows for unauthorized database access, data leakage, manipulation, and in some cases, complete system control. Such actions can disrupt services and pose a significant threat to overall business operations.

Reproduction

The vulnerability can be reproduced by sending a POST request to the '/admin/index.php' file with a crafted 'username' parameter that includes malicious SQL payloads. This can be done using tools like sqlmap, which automates the injection process and demonstrates the vulnerability by extracting database information or executing time-based blind injection techniques.

Remediation

To address this vulnerability, it is recommended to implement prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be applied to ensure that user input meets expected formats, blocking malicious data. Finally, database user permissions should be minimized, granting only the necessary privileges to the account used for database connections.
