Official What does the f say? Discussion

Official discussion thread for What does the f say?. Please do not post any spoilers or big hints.

Hello everyone,
Can anyone give me a hint on this one, I’m quite lost since I already was able to buy everything possible from the fox bar, including the Deathstar. I don’t really understand the way to proceed with this challenge.
Thanks!

i found something like ‘ctf/run_challenge.sh’. am i in the right direction?

I found a foat st*n vulnerability but I can find any way to exploit it. Can anybody give a little nudge?

This has nothing to do with the users :confused:

Glad you liked it :smiley:

I got a shell locally, but on the server with the correct libc version (I think at least) not.

Wow cool challenge~ Learnt something new.

Hi everyone,

I’m stuck on this challenge. I’ve used the f****t s****g vulnerability to leak all type of information. But now I can’t write a value to a known address. I know the theory but I don’t have enough space.

Any advice would be greatly appreciated.
Thanks in advance

Finally solved.

Tip for others: There are two vulnerabilites that must be exploited :wink:

Struggling to get the correct libc version here. Got a local shell. Can someone pm me with a hint?
