Irked

I finished the root flag, thanks to everyone who helped me with the tips!

I’m having a bit of trouble with the privilege escalation part. It feels like I’m on the right track and found something but I feel like I’m missing something. Could someone pm to know I’m on the right track? Any help would be appreciated :slight_smile:

For those who still struggle with this machine, the tip that helped me was to check for unusual binary file.

I couldnt find way to get user so i went straight to root. i didnt find this machine as easy as some say because i am not so used to this kind of files for priv esc

I have a problem with the root.
Could anybody help me ? i search a suggest on what to watch…

Hi

on irked box i have done user part
on priv esca part i found the v*****r file
and it is looking for /tmp/u*******s file but i dont know what to put inside that file
please pm me any hint or ref to some blog post!

thanks

Couldn’t figure out the user puzzle. Apparently the answer is right in front of me but I don’t do a lot of CTF so I just owned root instead. Would like someone to PM me the answer to user now that I’m done. Root definitely requires you to enumerate and scrutinize innocuous-looking binaries.

Thanks for the hints, everyone. Here’s mine: This privesc can get a bit sticky but it’s not difficult to exploit so don’t bash your head against the wall.

I’m completely stuck. I know I’m 100% overthinking this but I can’t seem to figure out the next direction. I found the initial foothold very easily. But now not only does the b***** file not make sense to me (I know what it references but everything I tried doesn’t work), I also took a look around for the potential root vector but I’m not seeing any strange binary file. I guess I’m just overlooking it? Can someone DM me with no-spoiler hints?

EDIT: I was absolutely overthinking. The b***** file is incredibly simple. Think back to your stego challenges and the tools you’ve used. The privesc was simple as well. What helped me was looking at the binary files in comparison to my attacking machine and comparing the two. Shoutout to @ZaphodBB and @natanrigailo for helping to shift my stuck mindset and give me the nudge I needed

Hello Guys, i have a problem with b***** file, i no have idea what do!!
Thank you to all

read the message -it tells you all you need to know

Thank you @ZaphodBB for all!!

got both user.txt and root.txt…i went straight to root though.

anyone want to guide me on the user priv? i can help with getting root.

got user as well now via steg. pm if you need assistance for user or root

thanks guys , rooted the box

The best ‘hint’ is
Something is not ON the page, something is IN (after you find file)

I’m stuck on Steg part of the .b****** could use some help!

YouTube, many tutorial about it

Managed to find p***.t**
what kind of hash is that? couldn’t manage to find how to crack it

the root is pretty easy. But how did you guys decode the user file? Can somebody PM me. Thanks

pm me!

can someone help me out with the beggining foothold? i think im looking at the right thing but im not sure

Like so many hints in this section…the way to find root is by looking for a file that’s normally not there. Think about what kind of file has the power (permission) to alter things that normally are restricted/protected? For the people who didn’t find it in the enumeration scripts…look closer.

Also for the ones that are asking help with “I found file x******z and don’t know what to do with it”…it’s a dead give-away. With the right find command you still give the answer, which can count as a spoiler.

I’m still on limited user.
Wtf! is this a SNES International Super Start Soccer cheat! ■■■! I love this game hahaha
