App - Script

I have spent a rather large amount of time on this challenge and I understand that the [Th1b4ud : spoil]. Can anyone assist me in this?

Code:

#!/bin/bash
echo hi > testy.txt
mv testy.txt /tmp/g_stuff/

You have found the vuln. Keep trying to exploit it !

Yes I understand the vulnerability. But I can’t get the file that is moved into cron.d to do anything.
