PHPGurukul News Portal SQL Injection Vulnerability in Category Editing Functionality

A critical SQL injection vulnerability has been identified in PHPGurukul News Portal Project version 4.1. The issue resides in the admin/edit-category.php file, where the 'category' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication or authorization.

Impact

Exploitation of this vulnerability allows unauthorized access to the database, enabling attackers to leak, modify, or delete data. Additionally, it could lead to full control over the system and disruption of services.

Reproduction

The vulnerability can be reproduced by sending a POST request to the admin/edit-category.php file with a crafted 'category' parameter that includes malicious SQL payloads. The injection can be verified by observing the application's response or by using a tool like sqlmap to extract database information.

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 rights to the account used for database connections.
