Narrative:
Air carrier X, MD11, on vector to cvg runway 18L ILS final. Unidented VFR aircraft with mode C flying along boundary of cvg class C (5-7 mi from airport) back and forth across the final approach course just below the GS. The MD11 had to level 'high' until passing the aircraft. Without knowing the VFR aircraft's intentions, both the controller and the PIC were concerned about the midair collision potential.
