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

@chillmechanic11 5 месяцев назад

When you didn't see the output for 22 port, it was because of your command. You did '> /dev/null' which made the succesful results go to null. What was needed is this: '2> /dev/null'

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!)

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

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.

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.

@mychanel9944 2 года назад

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 2 года назад

@savipats Год назад

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.

@aaryanbhagat4852 2 года назад

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 2 года назад

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 2 года назад

@@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 2 года назад

@@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.

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.

@euridicedeneuve8780 2 года назад

[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.
