The Turin giants came into the second leg with a 2-1 advantage and made no mistake despite being pressed all the way by Siena.
Alessandro Del Piero broke the deadlock on the stroke of half time, his 150th goal in a Juve shirt.
Mauro German Camoranesi doubled Juve's advantage shortly after the restart, but they were made to sweat before booking their place in the last eight as Nicola Ventola reduced the arrears with a 53rd-minute penalty.
Udinese booked their place in the next round with an impressive victory over Bologna.
Goals from Carsten Jancker, Marek Jankulovski and Mirko Pieri ensured a 3-0 victory for Udinese, who won the first leg 1-0.
Joining them in the next round will be UEFA Champions League holders Milan, who defeated Sampdoria 1-0 to secure a comfortable 2-0 aggregate victory.
Italian striker Filippo Inzaghi grabbed the night's only goal.
