There's a full ROC curve in Figure 2. Just eyeballing it, it looks like they get both sensitivity and specificity in excess of .9 in the top left corner (I didn't try to measure it precisely).

It would certainly be helpful to have more information about the over/undersampling.

I did miss that, oops. That said, it's again unclear if that curve is pre- or post- biased sampling. If it is on the original data it is quite good, but with a heavy biased sample fairly meaningless.

If it's not made clear, post-sampling analysis is the safe assumption.
