SEC_ERROR_REUSED_ISSUER_AND_SERIAL error when using Decrypt HTTPS websites using SSL/TLS in EAP using Firefox

Lee Paton

I am seeing this error intermittently when browsing in Firefox on a device with SSL/TLS decryption of HTTPS websites enabled. I have the ImportEnterpriseRoots setting enabled in Firefox to import the Sophos root CA. Browsing will work for a period of time and I can see looking at the certificate chain that the root CA is a Sophos one so HTTPS Interception is working. However, after period of time (usually a few hours) any sites I browse to will generate the following error SEC_ERROR_REUSED_ISSUER_AND_SERIAL. If I close and reopen all browser windows, I am able to successfully browse to the same sites again.

Googling this error points to articles that mention that deleting the certificates or CAs that cause the issue but this is not sustainable when we look to roll this out to 500 users. https://support.mozilla.org/en-US/kb/Certificate-contains-the-same-serial-number-as-another-certificate

Looking at the certificate authority in Windows for the Sophos Endpoint, it looks to be generated today. Is it a case that the certificate is not a static certificate but is one that changes regularly and could this be causing this issue?

    I've been seeing this as well for the last week I've had decryption enabled on my main work laptop.

    Sure enough there are regular "registering root certificate" events in the log file:  C:\ProgramData\Sophos\Sophos Network Threat Protection\Logs\SophosNetFilter.log:

    One interesting thing I noticed from your post is the local root certificate is valid from 2 years in the past.

    Note: This issue usually clears up after about a minute without closing any tabs or windows.

    I wasn't aware of that log file and just checked mine and I can see three entries this afternoon where a new root certificate is generated.

    I'm also seeing lots of the following errors. Not sure if they're related to the issue I'm having.

    I'm seeing 2730 instances of the SSL_do_handshake returned SSL error= 1 reason=1042 error in my log file that goes back just short of four hours.

    I hadn't spotted the year on the cert being 2 years old, I saw the same date and presumed it was created that day. My also also does seem to clear itself up if I leave it a period of time but I haven't been able to pin down what causes the issue to start in the first place and happens to fix the issue. today for example, I have had this issue more than usual, maybe 5 times it's happened whereas usually, it will happen once maybe twice a day.

    I'm also seeing a fair number of the "reason=1042" errors, which are always accompanied by the other three errors you listed.

    While I believe the issue is related to the root cert cycling regularly, the actual failure events seem to coincide with the "[certgen] cloned certificate", which would need to be re-cloned whenever the root cert is cycled.

    Virustotal has been the most common offender for me since I access it regularly, here's the full event stack of its' failure on my first attempt connecting today:

    seeing this today for internal self signed cert pages, which were working last week. only with firefox.

    But I think we can save our time and stop writing our beta testing results in the EAP forums. For me it's clear, they're abandoned. It's been a while since I saw someone from Sophos answering here.

    Looking into the internal investigations taking place surrounding this issue, a fix has been found that will be released in the next major update. At this time the release may still be a couple of months out.

    can you please improve this behaviour soon?

    We (you?) know, this happens, when IPS received updates on the endpoint, while firefox is open.

    It's just incomplete coding, if you are not able to display a message in the broswser like, "Please restart your internet browser to apply Sophos Security updates"

    Instead users only see irritating error "SEC_ERROR_REUSED_ISSUER_AND_SERIAL"

    Good afternoon,
    
I'm also having the same errors and without a definitive solution.
    Errors do not occur when disabling modules.

    in the rare case, sophos is reading here, this is just happening after Endpoint NTP64 has received updates due to new IPS signatures at 11:38Z time

    tried to open www.golem.de

    it happens with EVERY other website, except those, that are skipped from https decryption. e.g. all sophos.com websites work. After restarting firefox, all is OK again. This happens only on workstation with https decryption EAP installed and enabled.

    When will this problem be fixed? I have now all my customers that get these error when using Firefox. This answer is 2 month old and the last update doesn't fix this problem.

    we're trying if disabling TLS1.3 early Data in FF may be a workaround. but it needs time to validate this as the issue happens so randomly

    After i read you post we have disabled TLS 1.3 in Firefox but the problem still exists. It's a bit annoying. But in most cases this problem appears when the website is using TLS 1.3.
