What does it mean to enumerate (files or not files) blindly by timeout in Linux?
I'm doing a lab on hack the box. There is a flask application there, I was able to send my data to the exec function of this application... I tried a lot of things to get the output of what I sent... In general, I was advised to try "blind brute force on timeout" (time.sleep still added). Can someone explain what was meant? What does "blind search" mean and how to do it?

Answer 1

well, enumeration of files blindly means to enumerate files without seeing them.
That is, not being able to execute commands like ls, sort through some file names that may come to mind.
What names to check you already need to come up with on your own. Some thread README, .gitconfig, .profile, but that's more you have to assume.
