Fluid leak inside car

Well paper on the floor overnight came back with a light brown fluid looking conspicuously like power steering fluid. I know I have a bad leak, but into the cabin is kinda unbelievable. But if others have experienced the same who am I to argue. Besides, the car is not a daily driver, it stays garaged & no exposure to the elements. The steering box I'm sure needs a rebuild. Looks like the leak is more than I anticipated. Should I have it rebuilt or is there anyone out there with an exchange program? I'm still reluctant to believe this is the issue but the box needs fixing anyhow, I'll see if it solves this issue as well.
