App - Script

Hello Everyone

I’m stuck with my first challenge, the bash - system 1.
I created a folder in /tmp.
I compiled the program.
I copied the /bin/cat folder into mine.
I renamed the cat folder to ls.
I gave the cat folder (called ls) and my ch11.exe a chmod 4777.
And I changed the PATH (PATH=".:$PATH"; export PATH).

But when I run ./ch11.exe it returns: ls: /challenge/app-script/ch11/.passwd: Permission denied

Any hints appreciated! :)

PS: Yes, I read the related ressources.

You are pretty close..it must be a small mistake on your part, because you seem to have done almost all the good steps..

Create a temporary permission

The problem here is you have set the SUID bit of renamed ls folder using the current user.
You need to get the rights of the other user somehow.
