Official Passage Discussion

#159

I posted my views on this on the cyber badger and HTB official discords… Good box @ChefByzen … some of it felt a little too CTFy to me but then of course that is the way life works sometimes.

Foothold - some googling will land you at a starting point, some digging will land you at a method to gain access to a low-priv shell. [Pre-made works, but you won’t learn from it. use premade afterwards!]
User - Look at what is available to you with your low-priv shell. Search for juicy files that could net you loot. Trust me, you haven’t looked hard enough yet if you are stuck here. its all available for you.
Privesc - pay attention to what you have access to. attention to detail will get you moving forward
Root - more enumeration and google-fu will land you an article, read up and execute for your soon to be root shell

#160

root@passage:~# id
uid=0(root) gid=0(root) groups=0(root)

Shoutout to @TazWake for the help

I’m curious about the priv esc, what other commands can be run through there/how else can I use it? PM me if you know more about it.

#161

rooted!

Initial foothold was easy and user makes sense if you look right in front of your nose and think whether admins reuse same things for multiple people. I had a pretty good idea with how to get root but trying to understand the service and its syntax took me a bit.

Fun box nonetheless.
Send me a PM if you need help or nudges.

Got my first user.txt without looking at any hints here, pretty happy :), maybe I got lucky.

Working on root now !

Nice. Good luck on root.

#164

Really interesting machine, thx @chefbyzen, learned some stuff here.
Feel free to PM for nudges btw

#165

Someone mind dm’ing me? Stuck on getting user1. I’ve enumerated the whole dir and can’t fine anything of interest. Thanks!

#166

Good machine for OSCP preparation, try to think out of the box DM me for nudges

#167

Got root, thanks to some hints here and Gunroot.
Mainly a newbie to pentesting and Linux world in general so it’s fair to say I learnt a lot about what you can do :smile:

#168

No idea how to get user.txt, I feel like I’ve looked around everywhere, can someone point me to the right direction? thank you.

Its difficult to answer this because the simplest non-spoiler answer is to enumerate. Look in the files and folders. Make sure you know what you’ve found and dont assume because something looks like a random string of characters that it isn’t useful.

But there’s a lot of data to work through. Unfortunately, this is realistic - you might do a pentest and land on a box which has 30 user’s documents and you have to go through terabytes of tedious stuff to see if they’ve left credentials out.

The main thing I can say is dont go too far from where your shell lands. Look at the files. If its encoded, decode it. If its hashed try to crack it. etc.

#170

Is their a tool that can automate this enumeration process? I have tried to zip the interesting directory and copied it to my machine and I’ve been using grep with a certain ‘rocking’ wordlist hinted in this thread but so far the only thing I’ve managed to achieve is freezing my vm due to the grep errors because of unescaped characters in the wordlist. Am I on the right path or am I digging in the completely wrong direction?

Not that I know of, but if you found yourself doing this a lot it might be worth creating one.

You can possibly script it with some bash.

You might have pulled down too much data but you are definitely in the right area. I don’t think running grep with a wordlist will get you what you need.

#172

Thanks @ChefByzen, I enjoyed this machine a lot. Just right amount of CVE, guessing and enumeration.

Hints:
Foothold - check what is used and how old it is. Do it by hand if sploit fails.
User1 - search for interesting files, find interesting pattern. Maybe ask chef if he can help you.
User2 - check how can you login with that username. What would you use if you are User1?
Root - you are going places. Google if you are already famous?

#173

Rooted !
Took me about 2hours on how to get the bus hhhhhh

#174

Hey guys! I need a hint. So i have a ww-dta shell, got decrypted creds to pl and nv but i can’t drop to theirs accounts because w*-d*ta shell don’t take input, like su and ssh requires a key file. I should enumerate next too?

Have you tried getting a better shell?

#176

Rooted. Happy to take PMs but I may not check often.

How did you decrypt the creds of n*v,
I was only able to decrypt pl’s creds.

#178

Could someone give me a hint? I found the /CeN*/ L**** p*** and now i don’t know what to do with it, I barely found it almost by accident without the dirbuster
