Description

This module scans for hosts that support the SMBv1 protocol. It works by sending an SMB_COM_NEGOTATE request to each host specified in RHOSTS and claims that it only supports the following SMB dialects:

LANMAN1.0 Windows for Workgroups 3.1a LM1.2X002 LANMAN2.1 NT LM 0.12

If the SMB server has SMBv1 enabled it will respond to the request with a dialect selected. If the SMB server does not support SMBv1 a RST will be sent.


Usage

The following is an example of its usage, where x.x.x.x allows SMBv1 and y.y.y.y does not.

A host that does support SMBv1.

msf auxiliary(smb1) > use auxiliary/scanner/smb/smb1 msf auxiliary(smb1) > set RHOSTS x.x.x.x RHOSTS => x.x.x.x msf auxiliary(smb1) > run [+] x.x.x.x:445 - x.x.x.x supports SMBv1 dialect. [*] Scanned 1 of 1 hosts (100% complete) [*] Auxiliary module execution completed msf auxiliary(smb1) > services -S x.x.x.x Services ======== host port proto name state info ---- ---- ----- ---- ----- ---- x.x.x.x 445 tcp smb1 open

A host that does not support SMBv1

msf auxiliary(smb1) > use auxiliary/scanner/smb/smb1 msf auxiliary(smb1) > set RHOSTS y.y.y.y RHOSTS => y.y.y.y msf auxiliary(smb1) > run [*] Scanned 1 of 1 hosts (100% complete) [*] Auxiliary module execution completed

Options

The only option is RHOSTS, which can be specified as a single IP, hostname, or an IP range in CIDR notation or range notation. It can also be set using hosts from the database using hosts -R.
