CVE-2022-41352 Information

Description

An issue was discovered in Zimbra Collaboration (ZCS) 8.8.15 and 9.0. An attacker can upload arbitrary files through amavisd 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 amavisd automatically prefers it over cpio.
