Projectworlds Online Admission System SQL Injection Vulnerability in Admin.php

A critical SQL injection vulnerability has been identified in Projectworlds Online Admission System version 1.0. The issue resides in the admin.php file, where the 'markof' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, 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 manipulate database queries. This could result in unauthorized data access, data leakage, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to the admin.php file with the 'markof' parameter. The injected SQL payload can be crafted to exploit the time-based blind SQL injection vulnerability, using SQL injection techniques such as the 'AND (SELECT SLEEP(5))' payload to test for SQL injection vulnerability.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Input validation and filtering should be implemented to ensure user input conforms to expected formats. Additionally, minimize database user permissions and conduct regular security audits.
