Chapter 15: Client-Side Browser Exploits

You can interpret the preceding blob of HTML by breaking it down into the following
components:
??? I want to load an object having the identifier D27CDB6E-AE6D-11cf-96B8-
444553540000. If it??™s already installed, information about where it is installed
can be found in the registry under HKCR\CLSID\{D27CDB6E-AE6D-11cf-
96B8-444553540000}.
??? If the control is not yet installed, I want to download it from http://
download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab.
??? I need version 6.0.40.0 or higher. If my version is less than 6.0.40.0, I want to
download http://download.macromedia.com/pub/shockwave/cabs/flash/
swflash.cab and use that object instead of the object I already have installed.
??? This object takes a parameter named movie. The value to pass to this parameter
is ???http://www.apple.com/appletv/media/connect.swf???.
There are some very interesting security implications here when you think about an
attacker hosting an object tag and luring an unsophisticated user to the website.
