22/tcp filtered ssh

53/tcp open domain (unknown banner: Bind)

80/tcp open http Apache httpd

2222/tcp open ssh (protocol 2.0)

Vulnerability Exploited:

XDebug running on web server allows remote code execution.

Privilege Escalation:

Vulnerable docker container allows user to execute commands as the root user.

Exploiting the host:


Nothing found on the webapp

One interesting header

Searching online leads us to:


So build the exploit in burp

Modify the python script as follows

Start the exploit script with nc listening on port 8889.

You will get a python shell so execute a python command to send a shell to port 8889

Once you have a shell you will be inside a docker container

Check your IP address:

Looking around the file system we find that we have very few tools available but we found a .cap file

Move the file over to the docker webserver to download it locally.

Now crack with aircrack-ng

This password does not work for ssh with the users zeus etc

Also found this in the cap file:

Generate a userlist with as many things you can think of and try all the passwords it could be .

Turns out that the user is icarus and the password is the SSID

Login and we find a new text file

Add that to your hosts file

Now do dome dns recon

Looks like a port knocking sequence

Send the sequence to the main host which opens port 22 for about 5 seconds


Seeing how docker is running we will map the root directory of the host system to /tmp and see if we can read the flag.

Now we have the root flag we know we can play around with the file system.

We execute a reverse shell:

And receive our shell in return
