TAR Path Traversal in Zimbra (CVE-2022-41352)

Description

This module creates a .tar file that can be emailed to a Zimbra server to exploit CVE-2022-41352. If successful, it plants a JSP-based backdoor in the public web directory, then executes that backdoor. The core vulnerability is a path-traversal issue in the cpio command- line utlity that can extract an arbitrary file to an arbitrary location on a Linux system (CVE-2015-1197). Most Linux distros have chosen not to fix it. This issue is exploitable on Red Hat-based systems (and other hosts without pax installed) running versions: * Zimbra Collaboration Suite 9.0.0 Patch 26 (and earlier) * Zimbra Collaboration Suite 8.8.15 Patch 33 (and earlier) The patch simply makes "pax" a pre-requisite.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
