                 ColdFusion Information Exposure (CFCACHE Tag)

January 18, 2000 17:00 GMT                                        Number K-015
______________________________________________________________________________
PROBLEM:       Certain files that are not normally publicly available may be
               downloaded and used as system reconnaissance information by
               users with malicious intent.
PLATFORM:      Systems running ColdFusion Server 4.0x (all editions).
DAMAGE:        The information about a server's web document directory
               structure and URL parameters used to call site pages can
               provide useful information for planning an attack on that
               server.
SOLUTION:      Download the new CFCACHE.CFM file and follow the directions
               given in the advisory. The solution has been incorporated in
               ColdFusion 4.5.
______________________________________________________________________________
VULNERABILITY  The risk is MEDIUM. The information about the vulnerability
ASSESSMENT:    is publically available.
