0x01 代码分析

1、首先来看一下全局过滤代码/php_safe.php 第24-33行中：

//$ArrPGC=array_merge($_GET,$_POST,$_COOKIE);
foreach($_GET as $key=>$value){
StopAttack($key,$value,$getfilter);
}
foreach($_POST as $key=>$value){
StopAttack($key,$value,$postfilter);
}
foreach($_COOKIE as $key=>$value){
StopAttack($key,$value,$cookiefilter);
10. }

这段函数对 $_GET,$ _POST, $_COOKIE等全局变量调用StopAttack函数进行处理，可以发现如果是从$ _REQUEST获取参数，那么将绕过全局过滤防护。

2、漏洞文件位置1：/Admin/Lib/Action/MemberAction.class.php 第93-110行中：

function cartlist(){
$model = D('TradeView');
import('ORG.Util.Page');
$where ='';
if(!empty($_REQUEST['start_time']) && !empty($_REQUEST['end_time'])){
$where .= 'member_trade.addtime>='.strtotime($_REQUEST['start_time']." 00:00:00").' and member_trade.addtime<='.strtotime($_REQUEST['end_time']." 23:59:59")." and ";
}
else if(!empty($_REQUEST['start_time']) && empty($_REQUEST['end_time'])){
$where .= 'member_trade.addtime>='.strtotime($_REQUEST['start_time']." 00:00:00").' and member_trade.addtime<='.strtotime($_REQUEST['start_time']." 23:59:59")." and ";
10.         }
11.     else if(empty($_REQUEST['start_time']) && !empty($_REQUEST['end_time'])){
12.         $where .= 'member_trade.addtime>='.strtotime($_REQUEST['end_time']." 00:00:00").' and member_trade.addtime<='.strtotime($_REQUEST['end_time']." 23:59:59")." and ";
13.         }
14.     if(!empty($_REQUEST['keyword'])){
15.         $where .= "article.title like '%".htmlspecialchars(trim($_REQUEST['keyword']))."%' and ";
16.         }
17.     $where .='1=1';
18.             $count = $model->where($where)->count();
19.             $p = new Page($count,20);

2、漏洞文件位置2：/Admin/Lib/Action/MemberAction.class.php 第126-135行中：

function userlist(){
$model = M('member');
import('ORG.Util.Page');
$where ='';
if(!empty($_REQUEST['keyword'])){
$where .= "(username like '%".htmlspecialchars(trim($_REQUEST['keyword']))."%' or realname like '%".htmlspecialchars(trim($_REQUEST['keyword']))."%' or address like '%".htmlspecialchars(trim($_REQUEST['keyword']))."%') and ";
}
$where .='1=1';
$count = $model->where($where)->count();
            $p = new Page($count,20);
