Sometimes, we may encounter issues with file uploads after applying the Lockdown on ColdFusion installs. This error may occur when we are trying to upload files to the Webroot location; the reason behind it is the Lockdown installer will remove write permission for the service account on the Webroot, and any attempts to upload the file to Webroot will throw an error.

The solution is to change Webroot’s permission to allow writing, modification, or execution per the application requirements.
