- normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
Basic Usage
This module is a scanner module, and is capable of testing against multiple hosts.
msf > use auxiliary/admin/smb/upload_file
msf auxiliary(upload_file) > show options
... show and set options ...

NTLM::SendLM true yes Always send the LANMAN response (except when NTLMv2_session is specified)
NTLM::SendNTLM true yes Activate the 'Negotiate NTLM key' flag, indicating the use of NTLM responses
