Module Ranking and Traits
Module Ranking:
- 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/scanner/smb/pipe_auditor
msf auxiliary(pipe_auditor) > show options
... show and set options ...
msf auxiliary(pipe_auditor) > set RHOSTS ip-range
msf auxiliary(pipe_auditor) > exploit
Other examples of setting the RHOSTS option:
Example 1:
msf auxiliary(pipe_auditor) > set RHOSTS 192.168.1.3-192.168.1.200
Example 2:
msf auxiliary(pipe_auditor) > set RHOSTS 192.168.1.1/24
Example 3:
msf auxiliary(pipe_auditor) > set RHOSTS file:/tmp/ip_list.txt
Required Options
- RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
Knowledge Base
Description
The pipe_auditor
scanner will determine what named pipes are available over SMB. In your information gathering stage, this can provide you with some insight as to some of the services that are running on the remote system.
Verification Steps
- Do:
use auxiliary/scanner/smb/pipe_auditor
- Do:
set RHOSTS [IP]
- Do:
set THREADS [number of threads]
- Do:
run
Scenarios
msf > use auxiliary/scanner/smb/pipe_auditor
msf auxiliary(pipe_auditor) > show options
Module options:
Name Current Setting Required Description
---- --------------- -------- -----------
RHOSTS yes The target address range or CIDR identifier
SMBDomain WORKGROUP no The Windows domain to use for authentication
SMBPass no The password for the specified username
SMBUser no The username to authenticate as
THREADS 1 yes The number of concurrent threads
msf auxiliary(pipe_auditor) > set RHOSTS 192.168.1.150-160
RHOSTS => 192.168.1.150-160
msf auxiliary(pipe_auditor) > set THREADS 11
THREADS => 11
msf auxiliary(pipe_auditor) > run
[*] 192.168.1.150 - Pipes: \browser
[*] 192.168.1.160 - Pipes: \browser
[*] Scanned 02 of 11 hosts (018% complete)
[*] Scanned 10 of 11 hosts (090% complete)
[*] Scanned 11 of 11 hosts (100% complete)
[*] Auxiliary module execution completed
We can see that running the scanner "###uncredentialed" does not return a great deal of information. If, however, running a "###credentialed", you will find that the pipe_auditor scanner returns a great deal more information.
msf auxiliary(pipe_auditor) > set SMBPass s3cr3t
SMBPass => s3cr3t
msf auxiliary(pipe_auditor) > set SMBUser Administrator
SMBUser => Administrator
msf auxiliary(pipe_auditor) > run

Name Current Setting Required Description
---- --------------- -------- -----------
CHOST no The local client address
CPORT no The local client port
ConnectTimeout 10 yes Maximum number of seconds to establish a TCP connection
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
NTLM::SendSPN true yes Send an avp of type SPN in the ntlmv2 client blob, this allows authentication on Windows 7+/Server 2008 R2+ when SPN is required
NTLM::UseLMKey false yes Activate the 'Negotiate Lan Manager Key' flag, using the LM key when the LM response is sent
NTLM::UseNTLM2_session true yes Activate the 'Negotiate NTLM2 key' flag, forcing the use of a NTLMv2_session

Proxies no A proxy chain of format type:host:port[,type:host:port][...]
SMB::AlwaysEncrypt true yes Enforces encryption even if the server does not require it (SMB3.x only). Note that when it is set to false, the SMB client will still encrypt the communication if the server requires it
