Summary Reflective XSS Protection and ASP unicode messing

Reported 2010-08-23 11:39:49 PDT
The Reflective XSS Protection currently present in Chrome/Webkit fails to handle a weird unicode "pruning" made by ASP servers (where they substitute omoglyphs). The issue is well detailed in this blog post: http://hackademix.net/2010/08/17/lost-in-translation-asps-homoxssuality/

We could normalize these before comparison, but there's a long tail of complex transformations like this. It's unclear whether we're better off chasing that tail or letting these folks realize that magically substituting one character for another is a bad idea.
