첫 화면이다.

페이지 소스는 아래와 같다.

<html>
<head>
<title>Challenge 38</title>
</head>
<body>
<h1>LOG INJECTION</h1>
<form method=post action=index.php>
<input type=text name=id size=20>
<input type=submit value='Login'>
</form>
<!-- <a href=admin.php>admin page</a> -->
</body>
</html>

https://webhacking.kr/challenge/bonus-9/admin.php 에 접속하면 아래와 같은 창이 뜬다.

페이지 소스를 아래와 같이 수정한다. 즉, 8번째 줄의 input 태그를 textarea로 수정한다.

<html>
<head>
<title>Challenge 38</title>
</head>
<body>
<h1>LOG INJECTION</h1>
<form method=post action=index.php>
<textarea type=text name=id size=20>
<input type=submit value='Login'>
</form>
<!-- <a href=admin.php>admin page</a> -->
</body>
</html>

폼에 아래와 같이 입력 후 제출한다.

https://webhacking.kr/challenge/bonus-9/admin.php 에 접속하면 문제가 풀린다.
