I am currently trying to pwn the Unified machine from starting point tier 2. Unfortunately I can’t seem to get it right despite my best attempts. I cannot get a reverse shell on my netcat listener by using the jdni tomcat payload, despite jdni returning me the correct message upon sending the forget request to the unify server. It seems to me that the payload isn’t functionning properly, as it does not seem to prompt the server to connect back to the specified port on my machine (4444 in my case). Has anybody faced this kind of problem before?
