jules70 knows says that https://defendtheweb.net/extras/playground/election/?vote_id=62d784 return an error : Request denied by SuperSecureWAF 1.2b
in addition firefox say that in his dev tools (ctrl+shift+I) (keyboard shortcut) in this adress network tab shows : 400 Bad Request so http error 400
I know that with burpsuite, we can change error 400 to the state 200 (=all is OK, ok), so as there is no error the communication is made and we have the password.
But I have no many experiences with BS, I have see with youtube tutorial about that, I hope that in the future I will resolve this chall
I say all of that for help the people interesting in hacking
see you
