CVE-2022-27925
Overview
This vulnerability is a directory traversal flaw in the mboximport functionality of Zimbra Collaboration Suite versions 8.8.15 and 9.0. The root cause is improper validation of ZIP archive contents uploaded by authenticated administrators, allowing crafted archive entries to escape intended extraction directories. The affected component is the ZIP file extraction process within the mboximport feature, which fails to sanitize file paths before extraction.
Vulnerability Description
Zimbra Collaboration (aka ZCS) 8.8.15 and 9.0 has mboximport functionality that receives a ZIP archive and extracts files from it. An authenticated user with administrator rights has the ability to upload arbitrary files to the system, leading to directory traversal.
Impact
An attacker with administrator credentials can leverage this vulnerability to write arbitrary files anywhere on the file system accessible by the Zimbra server process. This can lead to unauthorized modification or replacement of critical system or application files, potentially enabling privilege escalation, persistence, or lateral movement within the environment. The prerequisite is possession of administrator-level access to the Zimbra system. Successful exploitation can result in full system compromise or disruption of mail services, impacting business operations and data confidentiality.
Solution
Synacor has addressed this issue in updated releases of Zimbra Collaboration Suite. Administrators should upgrade to versions beyond 8.8.15 patch 12 and 9.0.0 patch 24 as detailed in the Zimbra Security Advisories and Release Notes available at https://wiki.zimbra.com/wiki/Zimbra_Security_Advisories and https://wiki.zimbra.com/wiki/Zimbra_Releases/9.0.0/P24. These advisories provide step-by-step patching instructions and recommend immediate application of these updates to mitigate the vulnerability.
