Here at in.security we wanted to develop a Linux virtual machine that is based, at the time of writing, on an up-to-date Ubuntu distro (18.04 LTS), but suffers from a number of vulnerabilities that allow a user to escalate to root on the box. This has been designed to help understand how certain built-in applications and services if misconfigured, may be abused by an attacker.
We have configured the box to simulate real-world vulnerabilities (albeit on a single host) which will help you to perfect your local privilege escalation skills, techniques and toolsets. There are a number challenges which range from fairly easy to intermediate level and we’re excited to see the methods you use to solve them!
The image is just under 1.7 GB and can be downloaded using the link above. On opening the OVA file a VM named lin.security will be imported and configured with a NAT adapter, but this can be changed to bridged via the the preferences of your preferred virtualisation platform.
To get started you can log onto the host with the credentials: bob/secret
This is a boot2root VM and is a continuation of the Basic Pentesting series. This series is designed to help newcomers to penetration testing develop pentesting skills and have fun exploring part of the offensive side of security.
VirtualBox is the recommended platform for this challenge (though it should also work with VMware -- however, I haven’t tested that).
This VM is a moderate step up in difficulty from the first entry in this series. If you’ve solved the first entry and have tried a few other beginner-oriented challenges, this VM should be a good next step. Once again, this challenge contains multiple initial exploitation vectors and privilege escalation vulnerabilities.
Your goal is to remotely attack the VM, gain root privileges, and read the flag located at /root/flag.txt. Once you’ve finished, try to find other vectors you might have missed! If you’d like to send me a link to your writeup, enjoyed the VM or have questions or feedback, 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. There were lots of wonderful writeups for Basic Pentesting: 1, and I look forward to reading the writeups for this challenge.
I recently got done creating an OSCP type vulnerable machine that's themed after the great James Bond film (and even better n64 game) GoldenEye. The goal is to get root and capture the secret GoldenEye codes - flag.txt.
I'd rate it as Intermediate, it has a good variety of techniques needed to get root - no exploit development/buffer overflows. After completing the OSCP I think this would be a great one to practice on, plus there's a hint of CTF flavor.
I've created and validated on VMware and VirtualBox. You won't need any extra tools other than what's on Kali by default. Will need to be setup as Host-Only, and on VMware you may need to click "retry" if prompted, upon initially starting it up because of formatting.
A new OSCP style lab involving 2 vulnerable machines, themed after the cyberpunk classic Neuromancer - a must read for any cyber-security enthusiast. This lab makes use of pivoting and post exploitation, which I've found other OSCP prep labs seem to lack. The goal is the get root on both machines. All you need is default Kali Linux.
I'd rate this as Intermediate. No buffer overflows or exploit development - any necessary password cracking can be done with small wordlists. It's much more related to an OSCP box vs a CTF. I've tested it quite a bit, but if you see any issues or need a nudge PM me here.
Virtual Box Lab setup instructions are included in the zip download, but here's a quick brief:
Straylight - simulates a public facing server with 2 NICS. Cap this first, then pivot to the final machine. Neuromancer - is within a non-public network with 1 NIC. Your Kali box should ONLY be on the same virtual network as Straylight.
This virtual machine is having intermediate to medium difficulty level.
One need to break into VM using web application and from there escalate privileges to gain root access.
Gaining low or root privilege shell can be done in two ways (for both)
The links below are community submitted 'solutions' showing hints/nudges or possibly a complete walkthrough* of how they solved the puzzle.
Please note, there could be (many) more methods of completing this, they just haven't, either been discovered, or submitted. If you know something that isn't listed, please submit it or get in touch and we would be glad to add it.
* This is a spoiler. It could possibly show you a way of completely solving it.
Here you can download the mentioned files using various methods.
We have listed the original source, from the author's page. However, after time these links 'break', for example: either the files are moved, they have reached their maximum bandwidth limit, or, their hosting/domain has expired.
For these reasons, we have been in touch with each author asking for permission to mirror the files. If the author has agreed, we have created mirrors. These are untouched copies of the listed files. (You can check for yourself via the MD5 & SHA1 checksums which are individually displayed on their entry page. See how here).
We also offer the download via BitTorrent. We prefer that people use BitTorrent, however, we do understand that it is not as straight forward as clicking on a direct link.
To make sure everyone using VulnHub has the best experience possible using the site, we have had to
limit the amount of simultaneous direct download files to two files, with a max speed of 3mb
This is because the average file size is currently about 700mb, which causes our bandwidth to be high (couple of terabytes each month!). As this is a privately funded project, we believe we have chosen the best hosting provider for the limited budget.
If would you like to be able to download a mass, and at quicker speed, please use torrents as these will be seeded 24/7. For a guide on how to setup and use torrents, see here.
If you're the owner of a listed file or believe that we are unlawfully distributing files without permission, please get in touch here.
