【漏洞复现】CVE-2022-41678 Arbitrary JMX Service Invocation with Web Interface
漏洞信息
Apache ActiveMQ prior to 5.16.5, 5.17.3, there is a authenticated RCE exists in the Jolokia /api/jolokia.
| 组件 | 影响版本 | 安全版本 |
|---|---|---|
| Apache:ActiveMQ | < 5.16.6 | >= 5.16.6 |
| Apache:ActiveMQ | 5.17.0 - 5.17.4 | >= 5.17.4，>= 6.0.0，>= 5.18.0 |
Once an user is authenticated on Jolokia, he can potentially trigger arbitrary code execution. In details, in ActiveMQ configurations, jetty allows org.jolokia.http.AgentServlet to handler request to /api/jolokia org.jolokia.http.HttpRequestHandler#handlePostRequest is able to create JmxRequest through JSONObject. And calls to org.jolokia.http.HttpRequestHandler#executeRequest. Into deeper calling stacks, org.jolokia.handler.ExecHandler#doHandleRequest can be invoked through refection. This could lead to RCE through via various mbeans. One example is unrestricted deserialization in jdk.management.jfr.FlightRecorderMXBeanImpl which exists on Java version above 11. 1 Call newRecording. 2 Call setConfiguration. And a webshell data hides in it. 3 Call startRecording. 4 Call copyTo method. The webshell will be written to a .jsp file. The mitigation is to restrict (by default) the actions authorized on Jolokia, or disable Jolokia. A more restrictive Jolokia configuration has been defined in default ActiveMQ distribution. We encourage users to upgrade to ActiveMQ distributions version including updated Jolokia configuration: 5.16.6, 5.17.4, 5.18.0, 6.0.0.
Jolokia是一个JMX通过HTTP的桥接服务，允许通过HTTP请求来操作JMX MBeans。
漏洞的核心是FlightRecorder MBean，这是JDK 11及以上版本中提供的一个功能，用于记录内存、垃圾回收、调用栈等信息。攻击者可以利用以下方法进行攻击：
newRecording- 新建一个记录会话setConfiguration- 更改记录会话的配置startRecording- 开始记录stopRecording- 结束记录copyTo- 将记录的数据导出到文件
攻击者首先通过setConfiguration方法修改配置，将一些键名改为JSP代码。这样，在记录的数据中就会包含攻击者注入的JSP代码。然后，攻击者使用copyTo方法将包含恶意代码的记录导出到ActiveMQ的web目录中，从而在服务器上执行远程代码 。
背景介绍
Apache ActiveMQ is an open source messaging middleware developed by the American Pachitea (Apache) Software Foundation that supports Java messaging services, clustering, Spring framework, and more.

源码：https://github.com/apache/activemq
环境搭建
docker-compose.yaml：
version: '2'
services:
activemq:
image: vulhub/activemq:5.17.3
ports:
- "61616:61616"
- "8161:8161"
- "5005:5005"
启动容器：
$ docker-compose up -d
61616是工作端口，消息在这个端口进行传递；8161是Web管理页面端口。
访问http://127.0.0.1:8161/admin/即可看到web管理页面（账号密码都是admin）
漏洞复现
参考：https://github.com/vulhub/vulhub/tree/master/activemq/CVE-2022-41678
首先，访问/api/jolokia/list这个API可以查看当前服务器里所有的MBeans，其中有两个MBean可以在本次漏洞复现中进行利用：
第一个方法是使用org.apache.logging.log4j.core.jmx.LoggerContextAdminMBean，这是由Log4j2提供的一个MBean。攻击者使用这个MBean中的setConfigText操作可以更改Log4j的配置，进而将日志文件写入任意目录中。
poc.py位于附录，使用它来复现完整的过程：
python3 poc.py -u admin -p admin http://127.0.0.1:8161
但是这个方法受到ActiveMQ版本的限制，因为Log4j2是在5.17.0中才引入Apache ActiveMQ。
webshell被写入在/admin/shell.jsp文件中，访问http://127.0.0.1:8161/admin/shell.jsp?cmd=id并通过修改cmd传参即可命令执行：
第二个可利用的Mbean是jdk.management.jfr.FlightRecorderMXBean。
FlightRecorder是在OpenJDK 11中引入的特性，被用于记录Java虚拟机的运行事件。利用这个功能，攻击者可以将事件日志写入任意文件。
poc.py位于附录，使用它来复现完整的过程（使用--exploit参数指定使用的方法）：
python3 poc.py -u admin -p admin --exploit jfr http://127.0.0.1:8161
webshell被写入在/admin/shelljfr.jsp文件中：
