If you have a single 128-bit block data in cleartext and the exact same data encrypted with an unknown AES key (the key length is known, though), is there any possibility of determining that key other than brute-forcing?

Note: This is strictly for research purposes, I know that fiddling with crypto in real-world projects is a very bad idea.
