Obtain AES CBC key when I have IV, plain text and cyphered text
===

I am looking for a way of obtaining the key from this set of information, I know for a fact that we are using 16 byte blocks with CBC and I have the first 16 byte plaintext and cyphered, along with the used IV.

At the moment I can test if a key is correct by comparing the output, but I cannot bruteforce 16 character keys for obvious reasons, reading other posts it was my understanding that having the data I have it might be possible to get the key.

Any hint?
