Thanks for the info. I'm not sure if there was ever a danger because the Fantastico developer is saying the version packaged into Fantastico was done long before:
netenberg.com :: View topic - Wordpress Urgent Update to 2.1.2
But its better to be safe anyway. We applied some mod_security rules which should kill any hacking attempt if there is a vulnerable version on the server. If any legitimate pages are affected let me know.
