For those of you with wireless networks that rely on WPA2 for security, please consider checking out this vulnerability and correcting for it:
To simplify the information, this is a client-based vulnerability, not one that can be adjusted manually on your Access Points. Look for an update from your devices' vendor and apply it as soon as it's available, and you won't have to worry about this particular flaw.
If you manage wireless via NPM/NCM, you might just be able to easily confirm WPA2 is in play in your environment, and then list the clients connecting using it. That will give you the devices that need to be updated.
