wall tube

Hello, I have installed a new vanity and upon reinstalling the plumbing, I came across a few issues. I've include a picture to reference: I tried to maintain the wall tube that was previously there, but with the slight movement of the re-install I seemed to have jarred the seal at the wall...

The wall tube is 1-1/2" and the waste connector has a smaller inner diameter, so the waste arm won't slip into the stub. Is there some kind of adapter I'm supposed to use? Thanks!
