Try this:

db.executeDbCommand({ buildInfo : 1 }, function(err, buildinfo) {
  console.log('V', buildinfo.documents[0].version);
});

EDIT: shorter version using command():

db.command({ buildInfo : 1 }, function(err, buildinfo) {
  console.log('V', buildinfo.version);
});

To get a list of commands that you can execute:

db.command({ listCommands : 1 }, function(err, response) {
  console.log(response.commands);
});
