Security Known Issue

  • Attention: Zimbra would like to alert its customers that it is possible for them to introduce an SSRF security vulnerability in the Proxy Servlet. If this servlet is configured to allow a particular domain (via zimbraProxyAllowedDomains configuration setting), and that domain resolves to an internal IP address (such as 127.0.0.1), an attacker could possibly access services running on a different port on the same server, which would normally not be exposed publicly. So we urge our customers to review this configuration setting to ensure that there are no vulnerabilities are introduced.

What's New

Announcing Zimbra Video Server GA

  • The Zimbra Video Server is a WebRTC stream aggregator that improves Connect’s performance by merging and decoding/re-encoding all streams in a meeting. Refer to the admin guide for instructions on installing the Video Server on the systems.

Deprecation of Zimbra Server on Ubuntu 14.04, Oracle Linux 6 and CentOS/RHEL 6

With a number of supported operating systems entering the end of life, Zimbra will deprecate all Zimbra versions for Ubuntu 14.04, CentOS 6, Redhat 6 and Oracle 6 as of July 31, 2021. At this date, there will no longer be any patch release for 8.8.15 and 9.0.0 on these operating systems.

  • Ubuntu 14.04 end of life occurred on April 30, 2019
  • CentOS and RHEL 6 end of life occurred on November 30, 2020
  • Oracle 6 End of life occurred on October 2020

After July 31, 2021, Zimbra Support will provide best-effort support for the last patch release on the listed operating systems. However, any known or existing bugs will not be addressed and Zimbra Support encourages all customers to follow our recommended upgrade path to a supported OS version at your earliest convenience to ensure no interruption in your support services.

For more information about the direction Zimbra is taking with supporting future operating systems please check our blog.

For questions or guidance with upgrading your operating system please open a support case and our Support team is here to assist you.

Web UX - Admin

  • Zimbra now supports Two Factor Authentication (2FA) when logging in to the Administration Console. The user should use the same 2FA mechanism they have setup for their mail login.

Web UX - Classic

  • For the Chinese language, the date formats have been fixed and the Classic Web App and Admin Console now will display this data correctly.


Fixed Issues

Web UX - Classic

  • The date formats were not the same between the display and the printed forms of an email. It is now made consistent.
  • When a user has multiple external accounts and deletes more than two of them at the same time on the preference page, only the last account's folders were deleted (the user had to delete them manually later). This issue is now fixed.

Platform

  • Command-line utility zmmboxmove was failing in case the mailbox move operation took more than 100 seconds. With this fix, a new localconfig attribute has been introduced - zimbra_remote_cmd_channel_timeout_min which will control the timeout for mailbox moves. The default value is set to 10 minutes which can be further increased if needed.
  • Updating Ciphers and TLS attributes in local config were not getting reflected in LDAP. Due to mismatch of TLS protocol, send/receive of emails were affected and amavisd service failed to connect to LDAP. These issues have been fixed. Updating Ciphers and TLS attributes in local config now correctly gets reflected in LDAP.

NOTE: For this fix to work, TLSv1 needs to be disabled on the server. Restart zmamavisdctl to make the changes effective:

zmlocalconfig -e amavis_sslversion='!TLSv1'
zmamavisdctl restart

Zimbra Connect

  • The 'Pin video' action has been fixed and is now visible during a meeting both in grid and in cinema mode.
  • Now all the HTTP responses but the 404 error will contain the Content-Type header so Team can be used in conjunction with X-Content-Type-Options: nosniff header.
  • In the forward modal window, the conversations with cleared history were wrongly set at the top of the list.
  • Instant meeting’s modal windows will is no more shown twice on adding.
  • It is now possible for users to create spaces with no user.
  • Group invitation is now improved with the new option to allow users to show or hide the previous history of a group chat. Also in Instant meetings when a new user joins a meeting will not be able to see the previous history. On the other hand, in spaces and channels, history will always be visible. Moreover, when a user leaves a conversation or the conversation is deleted, the clear conversation’s data is removed.
  • During an instant meeting, on sharing the screen the view automatically changes to cinema and the new screen share session is pinned when Video Server is used.
  • In a meeting, users can send two different streams: one for webcam and one for screen share.
  • Now, an instant meeting is hosted on the server the user that creates the meeting resides on.

NG Admin

  • When the notifications list is empty, a status message is now shown to advise the admins to click the refresh button to update the list. A refresh button has also been added to refresh the list.

NG Backup

  • Fixed a bug that prevented the items in the subfolders to be properly restored inside its subfolder when restoring with the doUndelete command.
  • The restore inside the source folder is now the default behavior of the doUndelete command.
  • Fixed a bug that prevented the backup coherency check operation to properly fix the backup path when missing Drive’s blobs are present.
  • The debug logs have been improved, now they log each remote call to the store, and more in detail, now every file upload to remote storage is logged for each folder.
  • The handling of errors during a coherency check where the backup is being fixed has been improved, now if it is not possible to move files away from the backup path, an error will be thrown.
  • The Real-Time backup now saves account/COS/domain configuration too. On restoring an account/COS/domain, it is now restored also the whole item configuration.
  • Clarified the error message that the coherency check operation throws when a missing blob is found in the backup path.
  • The Zimbra indexing is now temporarily disabled while performing restore operations such as the external restore and the restore on a new account to improve the restore performances.
  • The restore operation has been improved to increase its speed.
  • Improvement in the working of restoration of appointments/calendar.

Zimbra Drive

  • Fixed a bug that prevented properly generate the extension of the zip file on sending a Drive folder via email in Zimbra Modern Web App.


Known Issues

  • None
