This Metasploit 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 utility 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 below and Zimbra Collaboration Suite 8.8.15 Patch 33 and below.
ce92bc8cd0b896bbf1bbebcee5677a9a8619813aaba32b6be0cfc98fba18d5b5Ubuntu Security Notice 2906-1 - Alexander Cherepanov discovered that GNU cpio incorrectly handled symbolic links when used with the --no-absolute-filenames option. If a user or automated system were tricked into extracting a specially-crafted cpio archive, a remote attacker could possibly use this issue to write arbitrary files. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Gustavo Grieco discovered that GNU cpio incorrectly handled memory when extracting archive files. If a user or automated system were tricked into extracting a specially-crafted cpio archive, a remote attacker could use this issue to cause GNU cpio to crash, resulting in a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.

However, it can be bypassed with symlinks. While extracting an archive, it will extract symlinks and then follow them if they are referenced in further entries. This can be exploited by a rogue archive to write files outside the current directory.

Additionally, a null pointer dereference in the copyin_link function which could cause a denial of service has also been fixed.
