DEDE采集大师官方留后门的删除办法

去除官方后门方法：安装好采集大师后，请立即删除 include目录下的dedesql.query.php文件，如已经安装过，有可能文件已被改名为arc.sqlquery.class.php，找到并删除即可。此文件可被利用来在无需登录验证的情况下查询网站数据库，并进行更新、删除、查询数据等操作。大家也可以自己测试一下是否如我所说，方法： http://你的域名.com/include/dedesql.query.php.php?dopost=viewinfo 输入以上网址，即可打开后门界面。 说实话，会故意留后门的程序，最好的方法就是别用。这个后门被发现了，天知道下一个所谓的新版本还会不会冒出更多的后门来。此后门文件代码如下： 
<p class="codetitle" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; background: rgb(242, 246, 251); width: 640px; clear: both; border-top: 1px solid rgb(0, 153, 204); border-right: 1px solid rgb(0, 153, 204); border-left: 1px solid rgb(0, 153, 204); border-image: initial; border-bottom: none; font-family: tahoma, arial, "Microsoft YaHei";'>
复制代码代码如下:
<p class="codebody" style='margin: 0px auto 3px; padding: 0px 3px 0px 5px; outline: none; line-height: 25.2px; font-size: 14px; background: rgb(221, 237, 251); border: 1px solid rgb(0, 153, 204); width: 638px; clear: both; font-family: tahoma, arial, "Microsoft YaHei";'>
