In April 2022, we became aware of a possible exploit affecting some of our products that was identified during testing and reported to us*. We are not aware of any exploits of this in the wild and started to release firmware updates in May 2022.
Our standard best practice recommendation is to always keep firmware up to date, but we recommend that you check that affected units are running at least the firmware version in the table below. To protect users until all firmware versions were available and to give time for upgrades no other information about the issue was released originally. The vulnerability has now been announced under CVE-2022-32548 and is related to a possible exploit of the router's Web UI login page.
