MS10-065 Microsoft IIS 5 NTFS Stream Authentication Bypass



This module bypasses basic authentication for Internet Information Services (IIS). By appending the NTFS stream name to the directory name in a request, it is possible to bypass authentication.

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/admin/http/iis_auth_bypass
msf auxiliary(iis_auth_bypass) > show actions
msf auxiliary(iis_auth_bypass) > set ACTION < action-name >
msf auxiliary(iis_auth_bypass) > show options
    ...show and set options...
msf auxiliary(iis_auth_bypass) > 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.
