Zimbra UnRAR Path Traversal
Posted by deepcore on August 6, 2022 – 8:36 pm
This Metasploit 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 Zimbra Collaboration versions 9.0.0 Patch 24 and below and 8.8.15 Patch 31 and below provided that UnRAR versions 6.11 or below are installed.
