In the slides of this talk, Prof. Gordon Kane explains about a year ago how he and his colleagues obtain a higgs of about 125 GeV from their M-theory phenomenological model for example (slide 20). But string phenomenology is a whole industry now ...
As explained here the higgs is the first spinless particle experimentally discovered. Since string theory contains many scalar fields (I`m among them :-P ...) it can be interpretted (optimistically) as a hint that string theory is on the right track. In addition, the article contains three cool ways to look at the higgs boson from a stringy point of view.
