Vulnerable Application
This module has been tested successfully against:
- Windows server 2019
- Windows server 2016
- Windows 10
Description
The smb_enumshares module, as would be expected, enumerates any SMB shares that are available on a remote system.
The module can also recursively go through each directory in each share and gather information about the files inside them.
On some systems such as Windows 7, it can also iterate over user directories and %appdata%.
Options
set RHOSTS [string]
This is the target host(s), see https://docs.metasploit.com/docs/using-metasploit/basics/using-metasploit.html for more information.
set SpiderProfiles [boolean]
This is used to enable the module to only spider user profiles when share is a disk share.
set SpiderShares [boolean]
This is used to enable the module to spider shares recursively.
set ShowFiles [boolean]
This is used to enable the module to show detailed information when spidering.
set Share [string]
Can be set to only enumerate over a specific share.
Verification Steps
- Do:
use auxiliary/scanner/smb/smb_enumshares - Do:
set RHOSTS [IP] - Do:
set THREADS [number of threads] - Do:

Credentialed - Windows 10 Target
As you can see in the previous scan, access is denied to most of the systems that are probed. Doing a Credentialed scan produces much different results.

SMBPass => simon
msf6 auxiliary(scanner/smb/smb_enumshares) > set SMBUser simon
SMBUser => simon

The disconnect on port 139 happens because Windows 10 uses SMB3, which operates on port 445 instead.
Credentialed - Windows server 2019
This scenario makes use of the Share option, that is used to pass a specific share to be enumerated. The module is
also being ran with inline options in this scenario.
