Redcross

So I’m able to login to the a**** panel and tinker with the fw/u*** settings, but I’ve been stuck for a couple days making any progress from there. I’m stuck in a jail with the account I’ve created, not optimistic about getting out. I was able to get RCE with an exploit on a certain mail service but I’m having trouble converting it to a shell. I’m thinking I need to find RCE from somewhere in the a**** panel, but having trouble locating it. Am I headed in the right direction?
