PHPGurukul e-Diary Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul e-Diary Management System version 1.0. The issue resides in the '/dashboard.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 attackers to execute arbitrary SQL commands, potentially leading to unauthorized database access, data manipulation, and in some cases, remote code execution.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/dashboard.php' with a crafted 'category' parameter that includes SQL injection payloads. The injected SQL code is executed by the application, allowing the attacker to manipulate the database or access sensitive information.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance overall application security.
