Allaire Security Bulletin (ASB99-03)
   Microsoft Internet Information Server Exposure of Source Code with
   "::$DATA"
   Originally Posted: February 4, 1999
   Summary
   As indicated on the Microsoft Web site, Microsoft IIS exposes the
   ability to use an NTFS attribute to read the source code of ASP, CFML,
   Perl and other files that are on a server. This is not a problem with
   ColdFusion Server itself, but it is an issue that can affect
   ColdFusion users. Allaire recommends that customers follow the
   instructions posted on the Microsoft Web site to address this issue.
   Issue
   This issue is clearly explained in the Microsoft Knowledge Base: "The
   native Windows NT file system, NTFS, supports multiple data streams
   within a file. The main data stream, that which stores the main
   content, is called DATA. Accessing this NTFS attribute directly from a
   browser may display the script code for the file." For example,
   accessing http://myserver/index.cfm::$DATA may yield the contents of
   the file itself, not the processed results of the file.
   Affected Software Versions
     * Any ColdFusion Server running on Microsoft IIS (1.0, 2.0, 3.0 or
       4.0)
       
   What Allaire is Doing
   This is not an Allaire product. We are recommending that customers
   reference the information at Microsoft's site to address this issue.
   What Customers Should Do
   There are several patches and workarounds available to correct this
   problem. These are detailed in the following Microsoft Knowledge base
   article (Q188806):
   [4]http://support.microsoft.com/support/kb/articles/q188/8/06.asp
   Note: The Knowledge Base article provides instructions for changing
   application mappings as one of the solutions. The same instructions
   apply to ColdFusion with the following information:
   Executable Path %System32%\iscf.dll
   .cfm::$DATA
   .dbm::$DATA
