Security researchers have discovered security shortcomings in the WPA2 protocol that threaten the security of wireless networks, even if they are running up-to-date security software. The hack involves generating arbitrary broadcast packets from a spoofed node that trick legitimate nodes in a targeted network into responding …
It's all relative.
If an "intruder" is intentionally given access to the wireless access point which is bridged onto the lan, why should anyone expect more security than if the intruder had connected directly to the lan?
We should also report on how intruders can gain unauthorized access by plugging into unguarded ethernet ports.
Untrusted people should not be allowed on unauthenticated/trusted lans wireless or not.

"We should also report on how intruders can gain unauthorized access by plugging into unguarded ethernet ports."
That's too short. You need to work on your presentation. If you could stretch that to over 500 words _then_ we'd have a security weakness.
