Description This module creates a RAR file that can be emailed to a Zimbra server to exploit CVE-2022-30333. 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 unRAR that can extract an arbitrary file to an arbitrary location on a Linux system. This issue is exploitable on the following versions of Zimbra, provided UnRAR version 6.11 or earlier is installed: * Zimbra Collaboration 9.0.0 Patch 24 (and earlier) * Zimbra Collaboration 8.8.15 Patch 31 (and earlier)
