PHPGurukul Online Course Registration SQL Injection Vulnerability in news.php

A critical SQL injection vulnerability has been identified in the PHPGurukul Online Course Registration application, specifically in version 3.1. The issue arises in the news.php file, where the newstitle parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized access to the database, 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 news.php file with the newstitle parameter. The request should include a crafted SQL payload that exploits the application's SQL query handling. 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 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.
