## PORT 8000 (HTTP)

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

|
|

|
|
|
|
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
|
|
|
|

|
|

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

|
|
|
|

|
|
|

|
|
|
|
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
|
|

|
|
|
|
Now commands can be run properly
|
|
|
|
<img src="https://imgur.com/zZgC9v9.png"/>
|
|
|
|
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/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`
|
|
|
|

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