Doh !!

Subject: [Full-disclosure] Fun with Foundstone

Things for a security company not to do in a webapp:

1. Do not auto-populate form fields on the page with customer names.

2. If you ignore rule number 1, don't use a simple, predictable id
for said auto-population.^2155

Rinse, increment, and repeat for a list of Foundstone
customers...or at least a list of companies they've let download

Now that's just plain sloppy.

Looks like they've been reading your blog, because this doesn't work anymore.

I wish it worked with the passwords, too -- it took me two weeks to get them to give me a login to their download site!

Anyway, this blog post just affirms the hours I spent coding an auto-populate page that uses our long-ish customer id hashed together with the UNIX timestamp of when their account was created. Hard to guess, and hard to guess one an unknown id based on a known ID.
