Upgrading USG 20 from 3.30(BDQ.7) to latest

BMJ

I have a USG 20 in use that I need to upgrade, if possible. Is this still supported or is it out of the question to upgrade to a current firmware? Let me know what other info is needed.

The USG 20 is no longer updated the newest firmware is ZyWALL USG 20_3.30(BDQ.9)C0.zip you can find on the FTP server.

OK thank you - is this vulnerable to https://www.zyxel.com/support/CVE-2020-29583.shtml? Is a patch available for that or should we replace the firewall?

Hi @BMJ

The USG 20 is immune to this vulnerability. This issue mainly exists on ZLD v4.60.

Thank you! I updated to the newest firmware available anyway.
