Recently checking my rankings for come keywords and I saw that my site was listed like this http://www.example.com/index.php
description here
indented >> http://www.example.com/index.php?A=B
indented >> description here
They are the exact same page and I've never had such paramaters as
?A=B I do have other parameters but not these, and because it's a dynamic page of course it will show content. Could my competition have submited the 2nd url to google in the hope that I would get penalized for duplicate content?
Should my code now be checking for expected parameters because of this? That will be headache, you have to make a list of valid parameters for every dynamic page.

[edit reason] switch to example.com - it cannot be owned [/edit]
