UAE striker Ismail Matar scored the winner in the stoppage time as the hosts set up a final clash with Oman, who beat Bahrain with the same result earlier on the same day.
Matar sent UAE to the semis with an injury-time goal against Kuwait in the group stage.
He now leads the scorers chart with four goals, one ahead of Saudi Arabia's Yasser Al-Qahtani.
Neither UAE nor Oman have won this tournament before.
