# Version: 1.0
# Tested on: Kali Linux
# Vulnerable page: quiz_question.php
# Vulnerable Parameter: "id"

Technical description:
An SQL Injection vulnerability exists in the Engineers Online Portal. An attacker can leverage the vulnerable "id" parameter in the "quiz_question.php" web page in order to manipulate the sql query performed.
As a result he can extract sensitive data from the web server and in some cases he can use this vulnerability in order to get a remote code execution on the remote web server.

Steps to exploit:
1) Navigate to http://localhost/nia_munoz_monitoring_system/quiz_question.php
2) Insert your payload in the id parameter

Proof of concept (Poc):
The following payload will allow you to extract the MySql server version running on the web server -
' union select NULL,NULL,NULL,NULL,NULL,@@version,NULL,NULL,NULL;-- -
