Phillip Hutchison whipped up a proof-of-concept on how advanced users could cheat and set the course as completed with a score of 100% (http://pipwerks.com/journal/2009/03/22/cheating-in-scorm/).
It poses an interesting problem as more and more cooperations are using SCORM based courses for certified training.
I just read on the www.adlgov.net page that they released a fix to this security issue. You can read more about it and download the instructions here: http://www.adlnet.gov/Technologies/scorm/SCORMSDocuments/SCORM%20Resources/Resources.aspx
