Google has found some query string urls

But I did a mod rewrite for SE friendly URL's

[MrSpeed]

Google has found some query string urls like
example.com/details.php?cat_number=2&prod_number=12345

I have a mod_rewrite to make the urls look like
example.com/2/12345/

I'm afraid of getting nailed with duplicate content.
I looked for the "leak" but can not find it.

How can I prevent this from happening?

You could try using their removal form. Or maybe try excluding googlebot from the page.

You might be able to do something with robots.txt

In general I think google just ranks one over the other, so I wouldn't worry too much about it.

That happened to me for a long time with a mod_rewritten postnuke CMS based site. We had the block on the right with links to "older articles" and completely forgot to mod_rewrite that (d'oh) so ended up with both in the index.

We were still #1 for those terms, google just ranked (what looked to me like) the first one it had indexed.

If you've now got thousands of pages indexed like that, it might be worth setting up a 301 redirect rule to point google and users to the mod_rewritten versions.
