could someone please reach out to me. I do have an exploit and I do get a connection back to my JR**L******* but i still do get a validation error (no context given) and my payload does not execute. I am not very familiar with the whole des********** topic and still dont fully understand how it works. so some advice or a link to a more detailed description would be highly appreciated. It also still might be that I am deep in a rabbit hole. so any advice is highly appreciated. thx. for more details on what I have been doing please pm me.
