The vulnerability

A remote code execution vulnerability exists in all series H/W revisions routers via the DDNS function in ncc2 binary file.

Required action

The impacted product is end-of-life and should be disconnected if still in use.

US federal civilian agencies were required to act by 25 April 2022 under BOD 22-01. The deadline is a compliance date, not a measure of severity — it says nothing about how dangerous the flaw is to anyone else.
