2009 and they are using URLs to pass data? I thought there was a push for security at Microsoft?

Using URLs to pass data is fine, if skeevy.

Using a publically visible tracking cookie to pass transaction data, though...

Microsoft spends more on security per line-of-code shipped than any company in the world. I have no idea how something this bad could have shipped. But I don't know the whole story.

One possible explanation: web pest tools like Burp filter out images from the request history, because you usually don't bother fuzzing requests for images.

Of course, you usually don't embed dollar amounts in images either.

This is funny, but I doubt there is any actual security flaw. I expect that Microsoft will verify these transaction later on with the vendor and throw them out.

I used Bing cashback to get 30% off my Macbook Pro from ebay. And I used it again at 20% off to buy a Nikon D60 (I think, or D80, it was for someone else) off ebay.

The funny thing is that Microsoft basically paid me about $200 to get a Mac (it was $200 because that's the max per transaction).
