You can reduce a bit of the flare effect with local contrast on Photoshop or Lightroom or some other softwares (I know more about these two).
As it is named, it's a contrast that is applied with a mask at the frontier (aarg... Sometimes english fails me) of differently lighted areas.
It's usually used for hazy pictures and helps with the flare problem.
It automated so you don't really need to know how it works :-)
