安乐业v3.0 代码审计

某基友在某地门户上班..网站总让人日..so..让吾等小菜帮忙看一下菜文勿喷抛砖引玉专用

只是粗略瞄了几眼..坑啊..

\common\lib\FCKeditor\editor\filemanager\upload\php\config.php

$Config['AllowedExtensions']['File'] = array() ;
$Config['DeniedExtensions']['File'] = array('php','php2','php3','php4','php5','phtml','pwml','inc','asp','aspx','ascx','jsp','cfm','cfc','pl','bat','exe','com','dll','vbs','js','reg','cgi') ;
$Config['AllowedExtensions']['Image'] = array('jpg','gif','jpeg','png') ;
$Config['DeniedExtensions']['Image'] = array() ;
$Config['AllowedExtensions']['Flash'] = array('swf','fla') ;
$Config['DeniedExtensions']['Flash'] = array() ;

根本木有过滤media有木有..

news\install\index.php.bak 这货竟然还带一个dede..虽然是bak备份文件..但是在apache中默认不解析bak...so 向上解析为php

<?php
/**
   *
   */
$insLockfile = dirname(__FILE__).'/install_lock.txt';
/*省略代码*/
foreach(Array('_GET','_POST','_COOKIE') as $_request)
{
         foreach($_request as $_k => $_v) ${$_k} = RunMagicQuotes($_v);
}

require_once(DEDEINC.'/common.func.php');

if(file_exists($insLockfile))
{
        exit(" 程序已运行安装，如果你确定要重新安装，请先从FTP中删除 install/install_lock.txt！");
}
?>

dede后台拿shell大家都懂..

典型的全局变量覆盖.悲催了...

其实就是dede二次开发的：http://www.17558.net/post/576.html

这东东，当年我还给客户装过……
