ColdFusion 5.0 and earlier on Windows systems allows remote attackers to determine the absolute pathname of .cfm or .dbm files via an HTTP request that contains an MS-DOS device name such as NUL, which leaks the pathname in an error message.
The GetFile.cfm file in Allaire Forums allows remote attackers to read files through a parameter to GetFile.cfm.
ColdFusion Server 4.x allows remote attackers to determine the real pathname of the server via an HTTP request to the application.cfm or onrequestend.cfm files.
