  • 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/vmware/vmauthd_version
msf auxiliary(vmauthd_version) > show options
    ... show and set options ...
msf auxiliary(vmauthd_version) > set RHOSTS ip-range
msf auxiliary(vmauthd_version) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(vmauthd_version) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(vmauthd_version) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(vmauthd_version) > 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

Vulnerable Application

vmauthd is the VMWare authentication daemon that is included with many VMWare products, including ESX(i), and Workstation.

Warning: There is a known condition where this module utilizes SSLv3, however this is disabled in Kali. Changing to SSLv23 will work on a default Kali install. This change was made for documenting this module. Please see #7225 for additional details and the fix.

Verification Steps

  1. Start msfconsole
  2. Do: use auxiliary/scanner/vmware/vmauthd_version
  3. Do: set rhosts
  4. Do: run

Scenarios

A run against ESXi 6.0.0 Update 2 (Build 4600944)

    msf > use auxiliary/scanner/vmware/vmauthd_version 
    msf auxiliary(vmauthd_version) > set rhosts 10.1.2.5
    rhosts => 10.1.2.5
    msf auxiliary(vmauthd_version) > run
