影响版本：
DEDECMS全版本
漏洞描叙：
DEDECMS后台登陆模板中的gotopage变量未效验传入数据，导致XSS漏洞。
\dede\templets\login.htm
65行左右
<input type="hidden" name="gotopage" value="<?php if(!empty($gotopage)) echo $gotopage;?>" />
由于DEDECMS的全局变量注册机制，该变量内容可以被COOKIE变量覆盖,可以在客户端持久化存储，***终导致一个XSS ROOTKIT。
漏洞危害：
管理员在触发DEDECMS任意的XSS漏洞(如留言本XSS)后，可以通过该漏洞永久劫持覆盖gotopage变量，在DEDECMS的后台登陆页面永久嵌入任意的恶意代码。
验证：
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。
