Hello,

I've just posted a new paper some of you may be interested in:   http://www.vsecurity.com/download/papers/WeaningTheWebOffOfSessionCookies.pdf

While it's primarily an argument for fixing HTTP authentication, it does contain information on a few weaknesses common in browsers, including password manager issues and user interface vulnerabilities.

Feedback is more than welcome.

Enjoy,
tim

Abstract



In this paper, we compare the security weaknesses and usability limitations of both cookie-based session management and HTTP digest authentication; demonstrating how digest authentication is clearly the more secure system in practice. We propose several small changes in browser behavior and HTTP standards that will make HTTP authentication schemes, such as digest authentication, a viable option in future application development.

Full-Disclosure - We believe in it.
