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!

C0m80 Boot2Root

https://3mrgnc3.ninja/2017/09/c0m80/

About

This is my third public Boot2Root, This one is intended to be quite difficult compared to the last two.

But again, that being said, it will depend on you how hard it is :D

The theme with this one is all about 'enumeration, enumeration, enumeration', lateral thinking, and how to "combine" vulnerabilities in order to exploit a system.

Important Note

Once you have an IP insert it into your attack system /etc/hosts like this:

[dhcp-ip-address] C0m80.ctf

This VM will probably be different to other challenges you may have come across. With C0m80 You will be required to log in locally in the VirtualBox console window at some point. This, I know, may 'rile' some of the purists out there that say you should be able to compromise a boot2root fully remotely over a network. I agree to that in principle, and in this case I had intended to allow vnc or xrdp access. Alas, due to compatibility problems I had to make a compromise in this area in order to get the challenge published sooner rather than later.

It should be obvious at what point you need to log in. So when that time comes just pretend you are using remote desktop. ;D

Sorry, I hope you can forgive me.

Difficulty Rating

[Difficult] but depends on you really

Goal

There is only one goal here. Become God on the system and read the root flag.

I Hope You Enjoy It.

Some challenge issue reported by @eliot

Looking forward to the write-ups!

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.

Introduction

I'm really interesting about security, love to learn new technologies and play CTF sometime. I’ve been enjoying creating hacking challenges for the security community. This is my first Challenge of boot2root, I was created some web challenge and solved others.I hope you will get some knowledges about my challenge. Thanks u Laiwon . I love you.

Difficulty

Difficulty level to get limited shell: Intermediate or advanced

Difficulty level for privilege escalation: Depend on You.

Goal

You will be required to break into target server,exploit and root the machine, and retrieve the flag. The flag will contain more information about my private info..

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, If you got big stuck, Try with Password start with "sec*" with nice wordlist. Ok.. Try Harder!..

~Happy Hacking!...

This is a small boot2root VM I created for my university’s cyber security group. It contains multiple remote vulnerabilities and multiple privilege escalation vectors. I did all of my testing for this VM on VirtualBox, so that’s the recommended platform. I have been informed that it also works with VMware, but I haven’t tested this personally.

This VM is specifically intended for newcomers to penetration testing. If you’re a beginner, you should hopefully find the difficulty of the VM to be just right.

Your goal is to remotely attack the VM and gain root privileges. Once you’ve finished, try to find other vectors you might have missed! If you enjoyed the VM or have questions, feel free to contact me at: [email protected]

If you finished the VM, please also consider posting a writeup! Writeups help you internalize what you worked on and help anyone else who might be struggling or wants to see someone else’s process. I look forward to reading them!

Instructions

The boot2root is a Debian virtual machine and has been fully tested using VMWare Workstation 12. The network interface of the virtual machine will take it's IP settings from DHCP.

Level

Beginner to Intermediate.

Description

Cyberry are eagerly anticipating the release of their new "Berrypedia" website, a life-long project which offers knowledge and insight into all things Berry!

Challenge

The challenge is to get root. Rooting this box will require a wide variety of skills and techniques, and you may find that there is more than one way to achieve this. Whilst the boot2root itself can technically be completed offline, you will almost certainly require some form of internet access (Search engine) at your disposal to move forward past some of the challenges. If you get completely stuck please tweet us @cyberrysec for a hint.

We really look forward to reading the walkthroughs on vulnhub of how you achieved root :-)

Difficulty:

Beginner

Description:

Mr. Derp and Uncle Stinky are two system administrators who are starting their own company, DerpNStink. Instead of hiring qualified professionals to build up their IT landscape, they decided to hack together their own system which is almost ready to go live...

Instructions:

This is a boot2root Ubuntu based virtual machine. It was tested on VMware Fusion and VMware Workstation12 using DHCP settings for its network interface. It was designed to model some of the earlier machines I encountered during my OSCP labs also with a few minor curve-balls but nothing too fancy. Stick to your classic hacking methodology and enumerate all the things!

Your goal is to remotely attack the VM and find all 4 flags eventually leading you to full root access. Don't forget to #tryharder

Example: flag1(AB0BFD73DAAEC7912DCDCA1BA0BA3D05). Do not waste time decrypting the hash in the flag as it has no value in the challenge other than an identifier.
