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 file '/manage-categories.php', where insufficient input validation of the 'id' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, leading to unauthorized database access, data manipulation, and potential leakage of sensitive information.

Impact

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

Reproduction

To reproduce this vulnerability, send a GET request to '/edms/manage-categories.php' with the 'id' parameter. Inject a payload that exploits the SQL injection vulnerability, such as one that uses 'updatexml' to extract database information. The application will respond with the requested data, demonstrating the successful exploitation of the SQL injection flaw.

Remediation

Users are advised to update to a version of PHPGurukul e-Diary Management System that addresses this vulnerability. Implementing prepared statements and parameter binding in SQL queries can prevent such SQL injection vulnerabilities. Regular security audits and minimizing database user permissions are also recommended.
