Can anyone give me a little help? I discovered my weakness is enumeration because I’m stuck with www data

To get around in a Linux system you need a username and some sort of credentials. See if you can find potential usernames.

If you have found anything remotely interesting, have you tried to utilize it in some way? See if you can find credentials.

You only need ‘cat’ and ‘ls’ command at this stage. Until you find some username and credentials, then you need an additional tool to test your findings.

Do you use any scripts to help with your enumeration ?

Rooted :blush:

Thanks for the original author of the hint “you’re not looking at two separate commands, they’re one command”!

Check the following:

  1. the file is in the correct format
  2. you are using the right options for john
  3. john hasn’t cracked it but decided to hide it from you (–show).

Alternatively try the Magnum Ripper version - its a bit more stable.

I’m 99% sure it’s in the correct format, I run the file that I curl for through ssh2**** and then feed that john. When I run john I specify the most common word list and the format. When I run --show i get “0 password hashes cracked, 1 left”

Ok - then use the alternative option.

@hrevans i had the same issue, i just added some thing like /h**e/ at the beginning of the file provided by ssh2**** and it works like a charm. btw it’s my firs user :smile:
i hope this helpful

I read a lot of “John” here, but uncle john isn’t needed.
Many ways to skin a cat, but using John here is like trying to explode the door of a safe, when the window right next to it is open…

Hi, Ive rooted the box earlier but not the john-route. Today I went back and want to manage to get in that way, but johns answer seems to be incorrect? DM me if you have any nudge/comment on that?

I’d be fascinated to know you bypassed the need for John (or some equivalent tool) on this box.

Happy to discuss in private if that is easier.

It is technically possible to do this without the need for john, but the chance to break the server for everyone in the process is pretty good.

Not sure what you have in mind, but what I talk about is completely safe and much easier than using john: it takes about zero effort and resources to do it.

You alter the box, which is bad, I agree. It might confuse other users, and provide unneccessary rabbitholes. So you better clean up after yourself fast, and probably do it in the vip-tier where you have the box for yourself.

BUT you dont break anything for other users if you know what you are doing :). add instead of replace.

Pretty fun box. A lot of CTF aspects. Root was incredibly easy. Feel free to DM for hints.

SSH is beating me down. The passphrase isn’t working, but no other errors are presenting. Pretty sure I have the correct password. Any gentle pushes?

EDIT: Honestly, just asking for help makes you smarter… I got it!!!

Nice and easy box to start on again after being away for more than a year.

The path I talk about adds and breaks nothing and allows for cleanup just as well, leaving all in tact that is, creating no other holes.

The “good” news is that this box retires on Saturday so people can be a bit less vague.

I can’t seem to get the root flag using the nano given in joanna, anyone know why

ignore that I made a dumb mistake

I am new to all this and this box is an amazing eye-opener. I learned a lot, especially enumeration and linux privilege escalation. many thanks to all the hints provided here. and a big thanks to @kbotnen . for your patience and very good hints. and of course, the user who created this box. can’t find the username (sorry about that)

i guess there is never such thing as “too much enumeration”. really enjoyed this box.

Rooted!
Thanks @TazWake & @thescriptkiddy
I feel so embarassed. Had it from the beggining, just got a little confused with the terminals lol

Hi, I’m locked in www-data, some clue where to look please. Thank you

You should take advantage from what the system gives to you, and do more fuzzing
