Yep, another security warning for IE6 and yet again it’s a nasty one.
It’s another active scripting exploit which potentially allows
anyone to do anything to your machine. The majority of these problems
care not a jot for proxies etc, and will work regardless of your access
method.
This is one of the growing list of problems which falls into the
cross-site scripting category of problem: allowing scripts from one
security domain (such as the Internet) to execute with the security
privileges of another domain (such as My Computer). I think you can see
the problem!
Presently Microsoft have no fix for the problem but are looking
into the issue. Industry experts suggest disabling Active scripting
(Not as easy as you woud think) or changing browser until a patch is
available.
