Allaire Security Bulletin (ASB00-07)
                 Microsoft Internet Information Server Exposure of Source Code with Malformed Hit Highlighting Arguments

                 Last Revision: April 10, 2000

                 Summary
                 Microsoft has announced a vulnerability for Microsoft IIS which exposes the ability to use a malformed URL 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 ISAPI filter that implements the hit-highlighting (also known
                 as "WebHits") functionality does not adequately constrain what files can be requested. If you provide a deliberately-malformed
                 argument in a request to hit-highlight a document, it is possible to escape the virtual folder. This can allow someone without
                 permissions to read any file residing on the same logical drive of the server that contains the Web Root folder. It does not allow
                 anyone without permissions to add or modify files." For example, accessing the URL:

                 https://www.yoursite.com/null.htw?CiWebHitsFile=/yourfile.asp%20&CiRestriction=none&CiHiliteType=Full

                 may yield the contents of the file normally available at https://www.yoursite.com/yourfile.asp itself, not the processed results of the
                 file.

                 Affected Software Versions

                       Any ColdFusion Server running on Microsoft Windows NT Server 4.0 or Microsoft Windows 2000 

                 What Allaire is Doing

                 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 (Q251170):

                 Please note: this issue and patch may not be required for all IIS users. Allaire customers should review all material in
                 the Microsoft Security Bulletin and related documents carefully before applying the patch. As always, customers should
                 test patch changes in a testing environment before modifying production servers.
