I just read about a post linked to from archived Michał Zalewski's archived post on wireless security and heard of an insider-only WPA2 flaw that lets anyone who knows the wireless password snoop on other people's traffic and inject their own in the middle of the communication.
I noticed that there are only 9 posts about hole196 on security.stackexchange.com and the only informative ones date back to 2012. I would expect a lot to change for the last over three years, thus the question - are there any feasible server-side solutions/workaround to the hole196 problem as of today, apart from using a VPN? If no, is there any stronger wireless encryption standard?
