NodeJS Recon: Basics
linux-security-recon-webservers | Level: Easy | Total Lab Runs: 0 | Premium Lab |
In this challenge we will look at the basics of NodeJS server reconnaissance. Please start the lab and answer the following questions:
- Find the port used by NodeJS web server and debugger.
- What content is returned when a query is made to the base directory of the target server?
- The server will reveal a flag when request is made for a specific directory path (e.g. http://<target_ip>/hello). There are two such flags. Retrieve both flags. The directories are present in this directory list: /usr/share/metasploit-framework/data/wordlists/directory.txt
- The server will reveal the flag when a request is made from a specific browser to “/secret” directory. Retrieve the flag.
- Find the name of main app file used by the NodeJS web server.
- List the number of scripts loaded (including node-internals) on the NodeJS web server using node-inspect.
- A breakpoint is set in the main app file. Trigger the breakpoint and use node-inspect debugger to view the source code of the main app file. The source contains a “Hidden Flag”. Retrieve the flag.
- 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 machine should be located at the IP address 192.X.Y.3.
- Do not attack the gateway located at IP address 192.X.Y.1

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 firstname.lastname@example.org 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.
