Do you use a Netgear router at home?
This week we saw a proof of concept code published for how to remotely take over 79 different models of Netgear routers through a flaw in their embedded HTTP server used for managing the device.
Not all routers have patches available, but you are encouraged to update your router’s firmware if it is in the list below. Some of these routers go back to 2007, and some are past end of life by many years so patches may never be created.
More info including effected firmware versions hopefully will be posted by Netgear soon. Netgear was notified of this at the beginning of the year (2020) and had asked for extensions to the disclosure to the public but the latest extension has expired, thus the disclosure going public. For now, checking for the latest firmware is the best path I know of, and checking again later this month and the next.
This was found by two independent security researchers at roughly the same time. Adam Nichols from GRIMM, a cybersecurity firm, says that 758 different firmware versions are affected, and I have included that listing as a text file.
