Re: The only workaround is to disable remote administration.
Still vulnerable to exploit from inside the LAN.
This means that if someone gets malicious code running on any PC inside your network, then they can use this vulnerability to take control of your router, and in turn use that to attack the other PCs on your network (fake DNS responses etc).
This is also a problem for coffee shops or other businesses who kindly share their Wi-Fi - any customer can hack their router.
