Kirilenko needed just over an hour to brush aside her Romanian opponent 6-0 6-2 as the world number 15 moved a step closer to claiming her first title of the season.
Kirelinko also beat Cirstea in last year's semi-finals before losing to Daniela Hantuchova in the final.
Fifth seed Lisicki defeated Kirilenko's compatriot Nina Bratchikova 7-5 6-3.
German Lisicki was playing in her first semi-final since 2011 after being hit by injuries last year, while Bratchikova was making her maiden appearance at this stage of a WTA tournament.
Lisicki said: "It was a little bit up and down in the beginning. I thought I couldn't serve too well and didn't have any ryhthm.
"I think I managed it in the second set, to get my rhythm back, and get my big first serve again.
"A couple of times when I had break points she served well and I missed some shots, but overall I'm happy with the match."
