How to reproduce the Apache ActiveMQ remote code execution vulnerability CVE-2016-3088
This article will explain in detail how to carry out Apache ActiveMQ remote code execution vulnerability CVE-2016-3088 recurrence, the quality of the article content is high, so Xiaobian share for everyone to make a reference, I hope you have a certain understanding of related knowledge after reading this article.
0x00 Brief background
ActiveMQ is an open source message-driven middleware software under the Apache Software Foundation. Jetty is an open source servlet container that provides a runtime environment for Java-based web containers such as JSP and servlets. ActiveMQ 5.0 and later versions integrate jetty by default. Provide a Web application that monitors ActiveMQ after startup.
On April 14, 2016, foreign security researcher Simon Zuckerbraun exposed multiple security vulnerabilities in Apache ActiveMQ Fileserver, which could allow remote attackers to replace Web applications with malicious code and execute remote code on affected systems (CVE-2016-3088).
ActiveMQ's web console is divided into three applications, admin, api and fileserver, where admin is the administrator page, api is the interface, fileserver is the interface to store files;admin and api need to log in to use, fileserver does not need to log in.
fileserver is a RESTful API interface. We can read and write files stored in it through HTTP requests such as GET, PUT, Delete, etc. Its design purpose is to make up for the defect that message queue operations cannot transmit and store binary files, but later found:
1. Its usage rate is not high
2. File manipulation is prone to vulnerabilities
So ActiveMQ has turned off fileserver by default in versions 5.12.x to 5.13.x (you can turn it on in conf/jetty.xml); after version 5.14.0, fileserver has been completely removed.
During the testing process, you can pay attention to the version of ActiveMQ to avoid detours.
0x01 Vulnerability Environment
Environment: vulhub.org/#/docs/
#Switch to the appropriate environment directory cd /root/vulhub-master/activemq/CVE-2016-3088#Open docker-compose up -d#View docker-compose ps
0x02 Bug recurrence
Write shell directly.
To write a shell, you need to write it in admin or api, that is, you need to log in, and you can't write a shell operation without a password.
The default password for this environment is admin/admin.
Visit http://ip:8161/admin/test/systemProperties.jsp
Get the path to the current system
Upload jsp pony, return 204, but do not parse under fileserver path
#Pony
Grab the bag with bp, PUT the pony
If successful, return 204 No Content and view it in your browser.
Then MOVE moves to api directory, if successful, return 204 No Content
Go directly to http://ip:8161/api/1.jsp? cmd=ls
Proof of Shell
