Microsoft Windows 7 / Server 2008 R2 SMB Client Infinite Loop

Created
05/30/2018

Description

This module exploits a denial of service flaw in the Microsoft Windows SMB client on Windows 7 and Windows Server 2008 R2. To trigger this bug, run this module as a service and forces a vulnerable client to access the IP of this system as an SMB server. This can be accomplished by embedding a UNC path (\HOST\share\something) into a web page if the target is using Internet Explorer, or a Word document otherwise.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/dos/windows/smb/ms10_006_negotiate_response_loop
msf auxiliary(ms10_006_negotiate_response_loop) > show actions
    ...actions...
msf auxiliary(ms10_006_negotiate_response_loop) > set ACTION < action-name >
msf auxiliary(ms10_006_negotiate_response_loop) > show options
    ...show and set options...
msf auxiliary(ms10_006_negotiate_response_loop) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
