Hello Kurt,
For CF 9.01, Go to {ColdFusion-Home}/lib/updates (for Server installation) or {ColdFusion-Home}/WEB-INF/cfusion/lib/updates (for Multiserver and J2EE installations) directory. If you have the hf901-00009.jar available there, that verifies you have the latest patch is applied.
Regards,
Anit Kumar
