PHPGurukul News Portal SQL Injection Vulnerability in About Us Admin Page

A critical SQL injection vulnerability has been identified in PHPGurukul News Portal version 4.1. The issue resides in the admin/aboutus.php file, where the pagetitle parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely without authentication, potentially leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database queries. This could lead to unauthorized data access, data manipulation, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to the admin/aboutus.php page with a crafted payload that includes a SQL injection in the pagetitle parameter. This payload can be designed to exploit time-based blind SQL injection techniques, such as using the SQL SLEEP function to create a delay that indicates successful exploitation.

Remediation

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, thereby blocking malicious data. Minimizing database user permissions is also advised, ensuring that the database account used by the application has only the necessary privileges.
