CVE-2022-45912Network attack vector

Authenticated code execution via traversable file uploads

Published Dec 5, 2022 · Updated Apr 24, 2025

Unrestricted file upload in ClientUploader in Zimbra Collaboration 8.8.15 and 9.0 allows remote authenticated users to execute code. ClientUploader accepts administrator-supplied files while allowing destination paths to traverse outside the intended upload directory. Administrator access to the network-facing utility is required, after which a placed file can execute code with the service context.
