SQLi, SSTI & Docker Escapes / Mounted Folders - HackTheBox University CTF "GoodGame"

[@znation4434]

John: *Literally shows the first docker escape I've ever seen* Also John: "Wow I'm a dumbo"

[@relix12]

Even though I can understand each step taken individually I wouldn't be able to string them together with my current skillset, but I did find solace in the fact that I had previously ran into and solved the bash -p hick-up. (*Insert Leonardo pointing meme here* The bash -p issue I ran across previously!)

[@Logan_144]

yo btw Thought I would just say, I recently found your channel and with every video I watch I learn something new, interesting, or another way of doing something I never even thought of! I love your content and I am pretty sure I will be a consistent viewer from now on. Keep up the great work John! :D

[@DHIRAL2908]

32:43 You can use SH instead. It won't require any other libraries and would work with SUID!

[@debarghyamaitra]

man the privesc was insane!! I didn't know that technique. Thanks John,

[@zacharycook8179]

just wow man.. watching you do this is so satisfying. So inspiring. WE. WANT. MORE!!!!!!!!

[@HundleBundle47]

"We're root supposedly....but we're supposed to be user. Did we skip that?!" John out here too good for these level 1 boxes haha

[@sannyboi7298]

Awesome video. Love your energy, your passion comes through and it’s contagious.

[@mychanel9944]

In case anyone is interested if you want to a fast check, beside a script in python to test a post with different values after js, if you are using Firefox, you right click on the post request, in the context menu there is an edit and resend command.

[@lupenn5914]

edit and resend on firefox is the most underrated feature

[@neiltropolis]

Love watching you work John! Thank you.

[@roguishowl3915]

Just started CTF and i love the challenges, my work is mind numbing, so these challenges are a great way to spend the remained of my work day.

[@chillytheprogrammer]

I can’t believe how it only has one star of difficulty. I could never get that far

[@somebodystealsmyname]

I would say it was slightly below OSCP level. But all technikes used you should learn for it.

[@gnorbsl4194]

I'm sure there was a moment in his life where he was like you. No one becomes an expert over night, just keep learning and one day one stars might be too boring for you.

[@DerMichael]

I think I would have to spend an hour on each step that took him 5 minutes. Always thinking about what I have and what I need and then searching for ways to exploit stuff, probably using trial and error many times.

[@neiltropolis]

Respect to your honesty. I've had a difficult time too.

[@younesmohssen8158]

@@somebodystealsmyname oof! This is a bit ‘below’ oscp level? Actually? I signed up for 60 days and I’ll be doing my oscp in about a month and couldn’t get a crack at this machine. So I’m even more worried now lolol

[@comradedad]

You are a master at your craft. Awesome video.

[@R3APERSW4G]

mounted file systems are dangerous, that was fun to watch!

[@epicmotivevideo]

Easy? How on earth .... I'd never get this as a noob. So much to learn ...

[@r34w0lf]

that was a cool privesc. learn't alot from this video. thanks!

[@TurtlesWrath]

4:30 "People are all excited about Battlefield" That didn't age well...

[@_JohnHammond]

I rewatched this video before uploading it (granted this was recorded ~4 months ago) and I thought it was hilarious I tried to make a contemporary joke. xD

[@Donder1337]

Dude this is insane man, never though it would be this easy.......

[@kaitlynk2145]

Would love a video of you setting up Ubuntu from scratch with how you install and what tools you install at the start

[@HAGSLAB]

I've been watching all your recent content and it's great as well, but I must say, after watching this video, that I really miss these CTF box videos 😊 Just my personal opinion though, make the content you feel like making at all times, it makes it better that way.

[@Makh161]

Great video. I understood everything except some of the subprocess ssti. What does setting stdout to -1 do? Cant seem to find documentation on that

[@danielstewart9584]

Brilliant video, thanks

[@charlesmarseille123]

this is gold, thanks a lot John!

[@patik237]

Wow I loved the video. Thanks

[@tolkienfan1972]

You could have used "enumerate" to quickly identify the index of Popen

[@Raser1995]

I wish I had so mush fun do it. I think I understand mostly what were you doing, but I never be able to do it by myself and come up with all that stuff. =)

[@bammer800]

That was awesome to watch

[@thewokeone9859]

ok n00b question. around @6:49 are you executing that python script from sublime text and then viewing the results in another tab?? if so, how so? thanks for this vid and you have a new subscriber....this makes me realize that I still have A LOT to learn.🙏🏼

[@savipats]

When you go to "Tools -> Build" you can see that it's possible to build your script with Ctrl+B. You might have to set it up first and make sure you use the correct interpreter, have the correct shebang line (#!/bin/python3 or w/e language u use) and have saved the script.

[@squ34ky]

Did you remove the ransomware stream? I was hoping to go finish it later. 😢

[@hexstaticloonatic4194]

Hey John, first of all great channel, love the content. Currently starting to learn about programming and am interested in white hat hacking side of things as well, thanks to you 👊 any resources you'd reccomend to get into the subject beyond hackthebox? Good luck with the channel anyway, cheers!

[@4x5au]

that privilege escalation was super cool!

My CRAZY mentor 🤣🤣😸😸

[@Infernottt]

Super interesting way to get to root

[@aaryanbhagat4852]

This might be a naive question but I do not understand upon looking at an input which kind of injection to use, for example upon looking at the name feild how john went for template injection and not some other sql one?

[@HAGSLAB]

Experience and knowledge of the stack in use. There was multiple references to Python and Flask in headers and HTML. Knowing that, John used his experience (could also been researched on the spot) to realize that a server side template payload is a viable option at that point to get server side code execution.

[@aaryanbhagat4852]

@@HAGSLAB i think you misunderstood, I just had a basic doubt regarding the technologies in use, let me explain: When we saw the sign up form he tried sql injection which is fine but when he found the form to edit personal information, I thought that the backend will again be SQL but he went for templates. How can one find which input has templates in the background and which has SQL?

[@HAGSLAB]

@@aaryanbhagat4852 Well, it's both in this case. Backend database saves the field contents; `{{ 7*7 }}`, but then that template string gets rendered (executed) server side before sending the result to the client. So that's exactly what I mean when I say that he knows this from experience and knowledge of the underlying stack.

It’s definetely not easy.

[@zachhockey]

Did I miss something? How'd he know the password was 'superadministrator'? Surely not just a lucky first guess?

[@HierImNorden]

Five months later I was wondering the same thing... Turns out he got that from the database in the very beginning. I had already forgotten about that part after all the SSTI shenanigans. The user just happened to use the same password for both his Linux user account and the website account.

[@mohamedsayed7363]

john would you please , give us a road map to what you became at the moment , so i can add what is missing : and catch up

[@euridicedeneuve8780]

[Question] Hi I have a question : at 13', once you've modified the "/etc/hosts" file to add a match between the local machine address & internal-administration.goodgames.htb, why is there a different webpage that renders once you type internal-administration.goodgames.htb ? Since it resolves to the local machine address, I don't understand why we shouldn't see the goodgames home page from the beginning. I'm missing something.

instwead of netcat (outdated on raspian os) use socat its built in raspian! everyone on kali should use socat aswell! so much better!
