Hardly news/vulnerability since reverse DNS is rarely reliable, and even
when it works people commonly do things like www1, www2, www3, etc. Even if
Sonic wall did everything, any website without reverse DNS would still be
reachable unless you start blocking IP's.

Names are for convenience, they are not terribly reliable for identifying
things you want to block on the web.
