    Is the repo disabled deliberately at your end or there is an issue?

    Cheers

      We are looking into your issue. I confirmed there are no issues on Zimbra 9 on both Ubuntu and CentOS.

    Thanks for the quick resolution Barry de Graaff! I confirm all is fine with the patch on Zimbra 8.8.15 on CentOS 7.

    cheers!

    Can you share some details (impact, possible mitigations, …) on the two security issues?

    * RCE through ClientUploader from authenticated admin user.
    * XSS can occur via one of attribute in webmail urls, leading to information disclosure.

    Thanks

    • Barry de Graaff November 23, 2022 at 12:18 AM #

      Mitigation of the security issues can be done by applying the latest patches. In case you want to do some other mitigation, please file a support case.

    Hi

    Zimbra 9 patch 28, after the patch upgrade we cannot send emails with attached files or images in the signature due this error: mail.SCAN_ERROR
    I found this error in mailbox.log file:

    java.net.ProtocolException: Got ‘UNKNOWN COMMAND’ from clamd, was expecting PORT

    Thank you

    • Barry de Graaff November 23, 2022 at 7:45 AM #

      For now you can workaround this issue as follows:


      zmprov ms `zmhostname` zimbraAttachmentsScanEnabled FALSE
      zmcontrol restart
