Have a VirtualBox set up with Vagrant and Ubuntu 12.04.1 LTS. Simply, can I be hacked? Do I have security concerns of my virtual server being detected?

For lofty, general questions like this, One can only reply with lofty, general answers. My answer for a question like this is simply:
Technically-imperfect people made the components mentioned, and technically-less-imperfect people can hack them, given the proper motivations.
That said the likelyhood is small, and someone having motivation to hack YOU is likely even smaller.
