Serious ASP.NET exploit
A serious ASP.NET exploit has been discovered. It can be used to decrypt viewstate, remotely log in as any user and potentially gain control over a server.

The exploit works by firing thousands of requests at a website, examining the returned error messages for information and eventually collecting enough information to derive the server's encryption key. Any ASP.NET website that doesn't return a static error page can be hacked using this method.
