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.

ColdFusion 4.5 and 5, when running on Windows with the advanced security sandbox type set to "operating system," does not properly pass security context to (1) child processes created with <CFEXECUTE> and (2) child processes that call the CreateProcess function and are executed with <CFOBJECT> or end with the CFX extension, which allows attackers to execute programs with the permissions of the System account.
