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/impacket/wmiexec
msf auxiliary(wmiexec) > show options
    ... show and set options ...
msf auxiliary(wmiexec) > set RHOSTS ip-range
msf auxiliary(wmiexec) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(wmiexec) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(wmiexec) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(wmiexec) > set RHOSTS file:/tmp/ip_list.txt

Required Options

  • RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'

  • COMMAND: The command to execute

  • SMBPass: The password for the specified username

  • SMBUser: The username to authenticate as

Knowledge Base

Verification Steps

  1. Install Impacket v0.9.17 from GitHub. The impacket package must be in Python's module path, so import impacket works from any directory.
  2. Install pycrypto v2.7 (the experimental release). Impacket requires this specific version.
  3. Start msfconsole
  4. Do: use auxiliary/scanner/smb/impacket/wmiexec
  5. Set: COMMAND, RHOSTS, SMBUser, SMBPass
  6. Do: run, see the command result (if OUTPUT is enabled)

Options

OUTPUT

When the OUTPUT option is enabled, the result of the command will be written to a temporary file on the remote host and then retrieved. This allows the module user to view the output but also causes it to be written to disk before it is retrieved and deleted.
