your host has php running as a CGI ( there is a similar thread ) and the version of php they have installed is known to be vulnerable.
it isn't ubb software from what i can tell.
that is, IF you installed one of the xx.xx.xxp2 versions that are imperative.

Understood and it is good to know that the problem is not with UBBThreads. Yes, I have SP2 patch installed. So, it would seem that it would be good to contact the host provider and mention what happened and it might be good to update their version of php.
