ColdFusion must execute as a non-privileged user.

Description
Privileged user accounts are accounts that have access to all the system resources. These accounts are reserved for administrative users and applications that have a need for such unfettered access. Because ColdFusion does not need to run with access to all the system resources, the ColdFusion services must be setup to execute as unprivileged users. This protects server resources, OS hosted applications, and organization resources should the ColdFusion application server become compromised.

For ColdFusion running on Windows: 1. Run the snap-in services.msc. 2. Locate the ColdFusion section of services. 3. Right click on each ColdFusion service and select "Properties". 4. Select the "Log On" tab. If any service has "Local System account" selected, this is a finding. 5. View the groups for each user account that was used to run a ColdFusion service by running the snap-in compmgmt.msc. 6. Expand the "Local Users and Groups" in the left pane under "System Tools" to view the "Users" and "Groups" folders. 7. Select the "Users" folder and the users will be listed in the right pane. 8. Right click a user that runs a ColdFusion service. 9. Select "Properties" on the menu. 10. Select the "Member Of" tab. If any groups are listed, this is a finding. 11. Click on the "Remote Desktop Services Profile" tab. If the "Deny this user permissions to log on to Remote Desktop Session Host server" is not checked, this is a finding. 12 Repeat steps 8 through 11 for each user that runs a ColdFusion service. ColdFusion running on Linux: 1. Locate the file coldfusion_11 by running the command: find / -name coldfusion_11 2. Change to the directory where the file is located. 3. Execute the command: grep -i -m 1 runtime_user coldfusion_11 4. The user being used to execute ColdFusion will be listed. 5. View the user within the /etc/passwd file. 6. Make note of the user id and group id. For example, if the line in the passwd file is cfuser:x:500:501:ColdFusion:/home/cfuser:/sbin/nologin, the user id is 500 and the group id is 501. If the user id or the group id is set to 0 (zero), this is a finding.
