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.

According to its self-reported version number, Zimbra Collaboration Server is affected by a multiple vulnerabilities:
including the following:

  - An attacker can upload arbitrary files through amavisd via a cpio loophole that can lead to     incorrect access to any other user accounts. (CVE-2022-41352)

  - Zimbra's sudo configuration permits the zimbra use to execute the zmslapd binary as root with     arbitrary parameters. This includes plugins in the form of .so files specified in a user-defined     configuration file. (CVE-2022-37393)

  - An information disclosure vulnerability due to an XSS attributes in the clsearch, compose and calendar     components of webmail. (CVE-2022-41349. CVE-2022-41350, CVE-2022-41351)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
