Bounty

This box is kicking my ■■■. I found a directory where I’m assuming I should be able to place a file to give me a reverse shell, but I can’t seem to figure out how to upload a file at all. I’ve thrown every enumeration tool I’ve got at this thing and come up empty handed. I thought I found an rce vuln but it seems that all I can do with it is DoS, which isn’t helpful. I’ve spent way too much time googling things related to the name of the box, the architecture of the web server, and the picture on the one static index page…

Can someone give me a hint on getting an initial foothold?
