Thank you to @Kevoenos for the link on the initial attack. It was what I was trying, but I was doing it in the wrong place, AND, if doing it at teh same time as other people this part is hard. IF a payload doesn’t work, wait a bit for a reset, and confirm someone else isn’t mucking up the attack. Try not to use a common file of interest to confirm access, use some other file in a directory that will always be there so that you know it was you, and not someone else
