Lab Walkthrough Video:

The target server as described below is running a vulnerable web server. You have to exploit the vulnerability and get a meterpreter session on the server.  Then, you have to perform the following tasks to complete the challenge!


  1. Check the present working directory on remote (exploited) machine.
  2. List the files present in present working directory of the remote machine.
  3. Check the present working directory on local (attacker) machine.
  4. List the files present in present working directory of the local machine.
  5. Get the flag value present in /app/flag1 file.
  6. Change the flag value present in /app/flag1, so that no one else can get the right flag.
  7. Change the present working directory to a suspiciously named directory in /app and read the flag from a hidden file present in that directory.
  8. Get the to local machine, open it using password 56784. The information given in the extracted file will give clue about the location of the another flag.
  9. Delete the .zip file from the directory.
  10. Print checksum of file mentioned in the extracted file (Refer to Q8).
  11. Check the PATH environment variable on the remote machine.
  12. There is a file with string “ckdo” in its name in one of the places included in PATH variable. Print the flag hidden in that file.
  13. Change to tools directory on the local machine.
  14. Upload a PHP webshell to app directory of the remote machine.


  • This lab is dedicated to you! No other users are on this network :) 
  • Once you start the lab, you will have access to a root terminal of a Kali instance
  • Your Kali has an interface with IP address 192.X.Y.Z. Run "ip addr" to know the values of X and Y.
  • The target server should be located at the IP address 192.X.Y.3. 
  • Do not attack the gateway located at IP address 192.X.Y.1 
  • postgresql is not running by default so Metasploit may give you an error about this when starting

The following activities are strictly prohibited on this website unless otherwise explicitly stated as allowed in the mission statement:

  • Using automated scanners
  • Using brute force attacks
  • Denial of Service attacks
  • Attacking other student machines in challenges where you might achieve a shell on the vulnerable system
  • Attacking the lab infrastructure

Users violating the above will be either temporarily or permanently banned from the website. 

If you are unsure about an activity, then please contact support to confirm that it is allowed on our website.

Technical Support for this Lab:

There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!

We currently provide technical support limited to:

  • Giving hints for a lab exercise
  • In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
  • A lab exercise fails to load or has errors in it

If you need technical support, please email  clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
