Brazilain forward Vitor Borges gave the Cheetahs the lead in the first half before Etoile FC pulled it back in the second period from a setpiece.
Selim Kaabi scored as the Cheetahs were unable to match the Frenchmen in the box as a corner was sworn in thus allowing Kaabi to nod home from close range.
But from their own set piece moments later, the Cheetahs took the lead again thank to Azhar Sairudin who took advantage of the Stars inability to clear the ball.
Azhar pounced on the loose clearance off a free kick and evaded a challenge before firing in with the outside of his right boot to give the Cheetahs winner.
