There's a new cable modem vulnerability called Cable Haunt that enables local and remote attackers to execute abitrary code on your cable modem. Through malicious communication with the modem, a buffer overflow can be exploited to gain control of the modem.

Question for NETGEAR - is the CM700 vulnerable to the Cable Haunt attack? Any plans to update the hw/fw to fix?
Thanks
