The remote bootstrap script is not part of the exploit at all. It happens in iTerm locally without any ssh session. I just installed iTerm2 on a fresh machine (no shell integration installed), ran the exploit (generated the file with the python script, ran `cat readme.txt` locally), and it worked. This is explained in the article in the "The core bug" section.
