Netgear Routers Will Need Firmware Update.

If you own a Netgear wireless router, especially the R6200, R6250, R6400, R6700, R6900, R7000, R7100LG, R7300, R7900, R8000, D6220, and D6400 routers and possibly other models are vulnerable to arbitrary command injection.  This is a security bug that could allow a remote attacker to access your router.  This vulnerability was announced by US-CERT on December 9th, and reported in Naked Security on December 12th.

Vulnerabilities such as this one can allow an attacker to add your router to an IoT botnet, such as the Mirai botnet we saw last year.

It looks like Netgear has prepared the firmware updates you need to fix this issue.  If you search Google for “Netgear <model number> firmware update,” of course entering your actual model number in the place where I have written <model number>, you should find what you need, including the instructions.
