Browse IIS Directory Structures

This article contains the complete project for an ISAPI Extension for exploring Web Servers with Microsoft Internet Information Server running.

Very often, such servers are not properly configured, so, system dlls like ISAPI Extensions are allowed to view the contents of each drive, including CDROM and other removeable drives.

Just open the project, compile it and upload the DLL to the WebServer of your choice. Obviously, take care that the server is running IIS. Then using your browser, enter the URL of the ISAPI Extension. The ISAPI Extension will read the directory of the server (if it is not protected by the operating system) and allow you to view it's contents as a HTML web page. The icons which you can see are stored on, because at this time I am not able to send the images while sending the HTML page to the Client via ISAPI.

For suggestions mail me or visit my Web site.

  • Anyone having problems impersonating in an ISAPI filter??

    I need to do this to list a remote directory via an NT share.
    I have tried the 'ImpersonateLoggedOnUser(token)' call, and also the SetThreadToken(handle,token).
    When performing a GetCurrentUser, I receive the username of the NT user I tried to impersonate, however I still have no access to the share. I get Error 5 Access denied from the FindFirstFile API.

    I have enabled all necessary rights on the local security policy to allow interactive logon, and act as part of the operating system. Both the LogonUser and ImpersonateLoggedOnUser return TRUE, and the handle is valid.

    I presumed that the thread calling the filter had some privileges disabled, but after listing the thread tokens privs, I realised that it had the LocalSystem rights (ALL privs)

    Please please please, does anyone have any ideas???
