Nebula Level 04 Description
This level requires you to read the token file, but the code restricts the files that can be read. Find a way to bypass it 🙂 To do this level, log in as the level04 account with the password level04. Files for this level can be found in /home/flag04.
In this exploit exercise, we analyze a code written in C language. It reads a token file based on the current user’s permissions which we need to bypass.
Basically we bypass this restriction in Linux by creating symbolic link to the file in question.
