## PORT 8000 (HTTP)

We can see this is a wordpress site so let's run `wpscan` on the site

<img src="https://imgur.com/J7HGIje.png"/>

<img src="https://imgur.com/wgiI1TN.png"/>

wpscan found a user name `bob` we can now try brute forcing the password

<img src="https://imgur.com/ymuYTKf.png"/>

Login with the credentials found

<img src="https://imgur.com/v5UQ9qk.png"/>

Now we can either manually upload a php reverse shell or use metasploit exploit

<img src="https://imgur.com/ULFPXUl.png"/>

We didn't get a proper meterpreter shell because of web shell exploit we used so we need to generate linux payload , upload and execute on the target machine

<img src="https://imgur.com/halR2va.png"/>

Open another meterpreter window and configure the listener

<img src="https://imgur.com/RhAdX4C.png"/>

Now commands can be run properly

Use metasploit's `autoroute` to do pivoting

<img src="https://imgur.com/cBNY93g.png"/>

Now we need to find what's running on docker conatiner so we can use metasploit's `auxiliary/scanner/portscan/tcp` module

<img src="https://imgur.com/bXNkEyQ.png"/>

In order to access the ports we found we need to use proxychains for that we run `socks` module on metasploit and use proxyfroxy to configure proxy for browser

<img src="https://imgur.com/wabq5Aw.png"/>

Verify that the port is added in the `/etc/porxychains.conf`

We can find `docker.sock` on the container which means we can create another container having host machien file system mounted on it 

<img src="https://imgur.com/ahgLzTq.png"/>

<img src="https://imgur.com/pjyVzWJ.png"/>

But to upload a static binary on that container there is no utility to download a file but we do have  internet avaiable on the machine so we can download `docker` as well but before that I downloaded `python3` on the container so I could get a stabilized shell

Run `apt update` and then `apt install python3`

<img src="https://imgur.com/uuv22cO.png"/>

<img src="https://imgur.com/xE8MdHu.png"/>
 

Download static binary and transfer it to target machine

Since we have `docker.sock` on our container we can list the imgaes being used 

`./docker -H unix:///var/run/docker.sock images`

<img src="https://imgur.com/NrKk09C.png"/>

Now to mount the host file system on the container

`./docker -H unix:///var/run/docker.sock run -it -v /:/host/ wordpress chroot /host`

<img src="https://imgur.com/4UYMBI9.png"/>

Add your generated ssh public key in `authorized_keys` and then ssh on the box as root
