Whether a given point is inside or outside a non-convex 3D tessellated (triangular mesh/ STL file) object?

I have a 3D, non-convex (very complex), triangular mesh ( = STL file i.e. triangular representation of surface of a 3-D object).
Now, a cube is intersecting with the STL object such that few triangles of the object are partially or fully inside the cube.
I want to know which vertices of the cube are outside the object.
