Multiplatform View State Tampering Vulnerabilities

Hrmmm… First CSPP from ShmooCon, tampering with the parameters in connection strings (primarily used for DBMS connectivity) and now what? VSTV or VSXSS, tampering with parameters in the __VIEWSTATE?
Is it real? This a question so far only answered with a pointer to this reference:
http://support.microsoft.com/kb/829743
as evidence that MS has known about this in ASP.NET for some time; and this video:
http://media.hacking-lab.com/movies/viewstate/
…on how it all supposedly works.
Dunno, it’s tough to see and my eyes are tired from producing this week’s episode. If this ISN’T a total hoax, it would seem 2010 might bring a string of these input validation type issues with configuration-type file-type goodies.
SpiderLabs has documented view state tampering vulnerabilities in three products from separate vendors. View states are used by some web application frameworks to store the state of HTML GUI controls. View states are typically stored in hidden client-side input fields, although server-side storage is widely supported. The affected vendors generally recommend that client-side view states are cryptographically signed and/or encrypted, but specific exploits have not been previously documented. These vulnerabilities show that unsigned client-side view states will ALWAYS result in a vulnerability in the affected products.
