Title

ColdFusion must disable the In-Memory File System. (Cat II impact)

Discussion

Application servers provide a myriad of differing processes, features, and functionalities. Some of these processes may be deemed to be unnecessary or too unsecure to run on a production DOD system. ColdFusion offers an in-memory file system. This feature can be used to have dynamic code execute quickly which in turns enables an application to execute quicker. This feature can also be used by an attacker to execute dynamic code that is erased and unrecoverable on system reboot making forensic analysis impossible.

Check Content

Verify the In-Memory File System setting. From the Admin Console Landing Screen, navigate to Server Settings >> Settings. If hosted applications are using the in-memory file system, this is not a finding. If "Enable In-Memory File System" is checked, this is a finding.

Fix Text

Configure the In-Memory File System setting. 1. From the Admin Console Landing Screen, navigate to Server Settings >> Settings. 2. Uncheck "Enable In-Memory File System". 3. Select "Submit Changes".
