ColdFusion is a programming language based on standard HTML that is used
to write dynamic webpages. When a page in a ColdFusion application is
requested by a browser, it is automatically pre-processed by the
ColdFusion Application Server. More information is available at:
Remote exploitation of and input validation error in ColdFusion MX 6.1
on IIS could allow the disclosure of file contents.
By supplying a filename of a file not 'associated' with the Coldfusion
plugin and appending ;.cfm or any other extension that is associated
with ColdFusion, it may be possible to view to contents of the files
that otherwise would be protected by IIS's access restrictions.
This vulnerability may expose sensitive files stored under the webroot,
bypassing access restrictions set in the IIS management system. In order
for the file to be read, it must be accessible to the user Coldfusion
is executing as. This vulnerability still requires knowledge of the
existence of a file of interest. It does not expose the directory
iDEFENSE has confirmed ColdFusion MX 6.1 on IIS is vulnerable.
Change the mapping rules for ColdFusion handled files to refer to
specific files instead of the default *.cfm, *.jsp, etc. It is also
possible to mitigate against exploitation by not storing sensitive
information within the webroot of any server. Storing the information
outside of the webroot may require changes to applications.
