It is based on a real world scenario I faced while testing for a client's site. Dedicated to Aunty g0rmint who is fed up of this government (g0rmint).

Does anyone need to know about that Aunty to root the CTF? No

The CTF is tested on Vmware and working well as expected.

Difficulty level to get limited shell: Intermediate or advanced

Difficulty level for privilege escalation: No idea

Give me feed back @nomanriffat

Many times while conducting a pentest, I need to script something up to make my life easier or to quickly test an attack idea or vector. Recently I came across an interesting command injection vector on a web application sitting on a client's internet-facing estate. There was a page, running in Java, that allowed me to type arbitrary commands into a form, and have it execute them. While developer-provided webshells are always nice, there were a few caveats. The page was expecting directory listing style output, which was then parsed and reformatted. If the output didn't match this parsing, no output to me. Additionally, there was no egress. ICMP, and all TCP/UDP ports including DNS were blocked outbound.

I was still able to leverage the command injection to compromise not just the server, but the entire infrastructure it was running on. After the dust settled, the critical report was made, and the vulnerability was closed, I thought the entire attack path was kind of fun, and decided to share how I went about it. Since I enjoy being a free man and only occasionally visit prisons, I've created a simple boot2root style VM that has a similar set of vulnerabilities to use in a walkthrough.

Introduction

Lately, I’ve been enjoying creating hacking challenges for the security community. This new challenge encapsulates a company, entitled – The Ether, who has proclaimed an elixir that considerably alters human welfare. The CDC has become suspicious of this group due to the nature of the product they are developing.

The Goal

The goal is to find out what The Ether is up to. You will be required to break into their server, root the machine, and retrieve the flag. The flag will contain more information about The Ether’s ominous operations regarding this medicine.

Any Hints?

This challenge is not for beginners. There is a relevant file on this machine that plays an important role in the challenge, do not waste your time trying to de-obfuscate the file, I say this to keep you on track. This challenge is designed test you on multiple areas and it’s not for the feint of heart!

Last Words

Whatever you do, do not give up! Exhaust all of your options! Looking forward to have OSCPs take this challenge. As always, good luck, have fun, God bless, and may the s0urce be with you.

Disclaimer:

By using this virtual machine, you agree that in no event will I be liable for any loss or damage including without limitation, indirect or consequential loss or damage, or any loss or damage whatsoever arising from loss of data or profits arising out of or in connection with the use of this software.

TL;DR - You are about to load up a virtual machine with vulnerabilities. If something bad happens, it's not my fault.

Level: Intermediate

Goal: Get root and read the flag file

Description:

Zico is trying to build his website but is having some trouble in choosing what CMS to use. After some tries on a few popular ones, he decided to build his own. Was that a good idea?

Hint: Enumerate, enumerate, and enumerate!

Xtreme Vulnerable Web Application (XVWA)

XVWA is a badly coded web application written in PHP/MySQL that helps security enthusiasts to learn application security. It’s not advisable to host this application online as it is designed to be “Xtremely Vulnerable”. We recommend hosting this application in local/controlled environment and sharpening your application security ninja skills with any tools of your own choice. It’s totally legal to break or hack into this. The idea is to evangelize web application security to the community in possibly the easiest and fundamental way. Learn and acquire these skills for good purpose. How you use these skills and knowledge base is not our responsibility.

XVWA is designed to understand following security issues.

• SQL Injection – Error Based
• SQL Injection – Blind
• OS Command Injection
• XPATH Injection
• Formula Injection
• PHP Object Injection
• Unrestricted File Upload
• Reflected Cross Site Scripting
• Stored Cross Site Scripting
• DOM Based Cross Site Scripting
• Server Side Request Forgery (Cross Site Port Attacks)
• File Inclusion
• Session Issues
• Insecure Direct Object Reference
• Missing Functional Level Access Control
• Cross Site Request Forgery (CSRF)
• Cryptography
• Unvalidated Redirect & Forwards
• Server Side Template Injection

Down By The Docker

Ever fantasized about playing with docker misconfigurations, privilege escalation, etc. within a container?

Download this VM, pull out your pentest hats and get started

We have 2 Modes: - HARD: This would require you to combine your docker skills as well as your pen-testing skills to achieve host compromise. - EASY: Relatively easier path, knowing docker would be enough to compromise the machine and gain root on the host machines.

We have planted 3 flag files across the various machines / systems that are available to you. Your mission if you choose to accept would be as following:

1. Identify all the flags (2 in total: flag_1 and flag_3) (flag_2 was inadvertently left out)

2. Gain id=0 shell access on the host machine.

This is a fedora server vm, created with virtualbox.

It is a very simple Rick and Morty themed boot to root.

There are 130 points worth of flags available (each flag has its points recorded with it), you should also get root.

It's designed to be a beginner ctf, if you're new to pen testing, check it out!

This vulnerable-by-design box depicts a hacking company known as H.A.S.T.E, or Hackers Attack Specific Targets Expeditiously, capable of bringing down any domains on their hit list.

I would like to classify this challenge with medium difficulty, requiring some trial and error before a successful takeover can be attained.

Hacker House are community sponsors at this year’s BSides London 2017 and, to celebrate, we have an exploit challenge for you. A key date in the UK security scene, it offers an alternative technical conference for the hackers and tech geeks to share war stories and learn. We are providing a challenge lab designed especially for the conference that attendees can sink disassemblers into. If you aren’t at the event, you can also hack along at home, but remember that prizes for solutions can only be claimed at our stand during the event! The challenge is provided in ISO format which you can boot in VirtualBox or any similar virtualisation software, heck you can even run it on an ATM if you like, but this is unsupported. If you solve our little brain teasing conundrums and beat the system to get root, the first three successful solutions presented to us at our stand can claim one of our awesome hoodies, check them out in our shop! This challenge is open to individuals, but if you do decide to team up, then let us know as only one prize can be claimed per solution. We are also giving several t-shirts away during the raffle so make sure you get your tickets!

Our challenge will test your elite hacking skills and requires web application, reverse engineering, cryptography and exploit abilities. It shouldn’t take the competent skilled hacker too much time, but if you do struggle then watch our social media feeds during the event for some tips to this adventure. You should run the challenge in Host-Only networking mode and on successful boot you will be presented with a console, similar to the one shown at the end of this post. You should solve the challenge from a network perspective, only solutions using this route will be accepted for prizes (unless they are really cool!).

The goal of the challenge is to hack the ISO, level up your skills and get root, come and show us how you did it if you want to claim your prize! If you are struggling with the configuration of our challenge, you can check out our training course free module, which details steps for configuring a similar lab. You can find details and upcoming dates of our training here.

Happy hacking and remember sharing is caring so post (tweet us @myhackerhouse!) or email a solution and let us know about it after the event. We will share links to the best of them on this blog! May the force be with you, young padawan, and remember that hacking isn’t just a skill – it’s a survival trade.
