CVE-2022-41352Known exploitationPublic exploitNetwork attack vector

Unauthenticated code execution via cpio path traversal

Published Sep 26, 2022 · Updated Sep 10, 2026

Path traversal in Zimbra Collaboration 8.8.15 and 9.0 allows remote attackers to execute code by emailing a crafted archive. Amavis falls back to cpio when pax is absent, and cpio follows traversal paths in attachment entries to write a JSP beneath the public Jetty web root. Exploitation is unauthenticated but requires a server without pax; successful writes expose a web shell and the server's mail data.
