Vulnerable to NetUSB hack? AC2600 R7450

[ecomike]

SentinelOne published a report detailing a NetUSB vulnerability in Kcode's firmware software that allows hackers to take over a router from the WAN via port 20005.

Will NETGEAR be releasing update firmware to fix this bug?

How can I close port 20005?  (and please don't reply that it is essential for proper functioning... this port should never have been available over the Internet, and it has a stack overflow that opens the router to complete takeover.)

So have to tested this on your router? 

How do you know if yours is effected?

Test with GRC | ShieldsUP! — Single Port Probe from within your network.

R8500 firmware 1.0.2.156 (from December 2021) predates this vulnerability, and unfortunately seems to cause DHCP to sporadically fail - creating problems with pretty much every web site.

Echoing the query to @netgear - is there an updating about to be released?
