what's about the Firefox SEC_ERROR_REUSED_ISSUER_AND_SERIAL issue with HTTPS decryption

My feeling is, Sophos does not know about the Intercept-X EAP forums.

So I put this to focus here. Maybe one of the Sophos members can bring some light into this issue, it this is on Sophos' screen and will be fixed?

Thanks.

  • There are several issues related to Modern Web that our development team has been working on. Some fixes will be rolled out in the 2022.1 release of the Sophos Central Endpoint agent, which may help with the certificate issue you are experiencing. 

    Where Chrome, Edge, and Opera browsers are affected by the SNTP service stopping and re-starting, this issue will be fixed with the 2022.1 release. I have not gotten confirmation that this will apply to Firefox as well, though some changes to the way certificates are handled are planned.

    We will have more information to share regarding when you can expect the update by early next week. If you would like to test the update while it is in it's early phases, I recommend opening a support case with our team.

  • that's very good news.

    Can you share a note here, when the update has been released in EAP? It's hard to track if individual apps have been updated on Sophos EP products.

  • Customers already running Sophos Core Agent version 2022.1 will receive an update today addressing the following advisory. 
    - wfplwfs.sys BSOD occurring on devices after 2022.1 Central Update

    The underlying issue will still need to be investigated with Microsoft, though some changes have been made to prevent the issue from occurring. I have reached out to get further clarification on when this Core Agent update will roll out to other customers and will follow up on this thread to keep you informed.

  • The core agent update will begin its release cycle on the 21st of June. Unfortunately, the firefox issue is still being investigated, though there are a number of fixes that will be addressed with this release. 

    If you have devices that are not yet using the SDDS3 updating mechanism, you can enroll these devices into the New Endpoint Protection Features EAP in order to receive this update.
