Zimbra not affected by log4j (CVE-2021-44228)
After intensive review and testing, Zimbra Development determined that the 0-day exploit vulnerability for log4j (CVE-2021-44228) does not affect the current Supported Zimbra versions (9.0.0 & 8.8.15). Zimbra Collaboration Server currently uses log4j1 version 1.2.16 which doesn't contain the lookup expression feature that is found within versions 2.0 to 2.17, which is the cause of the vulnerability. Also, Redhat (CVE-2021-4104) vulnerability does not affect the Zimbra Collaboration Server version (8.8.15 & 9.0.0). For this vulnerability to affect the server, it needs JMSAppender, which the ZCS Server does not use, and the ability to append configuration files.

Unless your web clients are on the same network as the Zimbra server (no NAT between them), you'll need a TURN server for video chats to work. For group text and video chats, you'll need a Talk (Connect) license for each user who is to organize group texts/chats. Just like Zoom: anyone can join a Zoom meting without a license, but organizing a meeting requires a license.

Hope that helps,
Mark

@Mark
All my web clients are
on the same network as the zimbra server.
Is it enough to install TURN server or is some
configuration of this server still required?

You’ll need a TURN server if the web clients are not on the same network as the Zimbra server.
