My guess is "information on this is needed", but I still don't understand why it's hasn't been and not haven't been. I know that haven't been is used for when in a sentence like:
I haven't been there in ages.
or
We haven't been there in ages.
So my vague guess is that "hasn't been" is used for uncountable nouns? Please correct me if I'm wrong.
There isn't a problem. (singular) - There hasn't been a problem. There aren't any problems (plural) - There haven't been any problems. There isn't any information. (uncountable) - There hasn't been any information.
