An issue was discovered in Zimbra Collaboration (ZCS) 8.8.15 and 9.0. An attacker can upload arbitrary files through amavis via a cpio loophole (extraction to /opt/zimbra/jetty/webapps/zimbra/public) that can lead to incorrect access to any other user accounts. Zimbra recommends pax over cpio. Also, pax is in the prerequisites of Zimbra on Ubuntu; however, pax is no longer part of a default Red Hat installation after RHEL 6 (or CentOS 6). Once pax is installed, amavis automatically prefers it over cpio.

This is I think the 6th major issue with Zimbra this year. It’s not really their fault, they use Amavis which uses cpio which is vulnerable to CVE-2015-1197, but the attack surface for incoming emails is HUGE.

Not to mention, this is one of several vulnerabilities this year that was being exploited in the wild before being discovered, which means Zimbra is an active target for the Bad Guys.

If you’re still using Zimbra, you might want to seriously reconsider. I betcha there are others, and they’re probably being exploited.
