Firmware 4.3.8.1 & expired certificate 30th May 2020

Andrew Meek

We're currently running 4.3.8.1 across all web appliances / single management appliance (it's been stable, we've had random issues in the past and do not update unless a specific reason forces us to..).

Today we experienced https scanning issues with some sites. All sites scanned through SSL Labs showed an expired cert 30th May 2020. Relating to this article:-

https://thesslonline.com/blog/sectigo-addtrust-external-ca-root-expiring-may-30-2020


Has anyone else had https inspection issues today on later firmware versions 4.3.9, 4.3.9.1 or 4.3.10 ??

Does the following bug fix listed in 4.3.9 release notes cover this specific issue?

NSWA-1634

The trusted CA certificates used for certificate validation have been updated.

Does updating to later versions replace the appliance cert used for https inspection?

 

Interested in comments from Sophos dev team if they are on this channel.

Thanks in advance!

    ... the problem has not only existed for 14 days.

    I have noticed the first occurrences in UTM - 9.701-6 increasingly since Jan 2020.
    So far, however, I was of the opinion that the problem was on the opposite side (of the respective homepage) because the message "certificate has expired" was always written out in conjunction with the target URL.

    I hope for a quick fix by Sophos.

    ... but without an appointment it does not seem to be so urgent.
