An attacker can upload arbitrary files through amavis via a cpio loophole (extraction to /opt/zimbra/jetty/webapps/zimbra/public) that can lead to incorrect access to any other user accounts. Zimbra recommends pax over cpio. Also, pax is in the prerequisites of Zimbra on Ubuntu; however, pax is no longer part of a default Red Hat installation after RHEL 6 (or CentOS 6). Once pax is installed, amavis automatically prefers it over cpio.","cvss_version":"3.1","cvss_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","base_score":9.8,"base_severity":"CRITICAL","attack_vector":"NETWORK","privileges_req":"NONE","user_interaction":"NONE","scope":"UNCHANGED","impact_c":"HIGH","impact_i":"HIGH","impact_a":"HIGH","cwe_ids":["CWE-22"],"in_kev":true,"kev_date_added":"2022-10-20","kev_ransomware":true,"epss_score":0.95478,"epss_percentile":0.99869,"cap_rule_version":"0.1.1","stage":"INITIAL_ACCESS","req_access":"NONE","req_vector":"NETWORK","req_user_interaction":false,"grant_access":"USER","caps":["CODE_EXEC","INFO_DISCLOSURE"],"terminal":false,"cap_confidence":"high","ingested_at":"2026-09-18T10:11:43.984950+00:00","first_seen":"2022-09-26T02:15:10.733000+00:00","kev_first_seen":"2022-10-20T00:00:00+00:00","novelty_score":0.0,"novelty_reasons":[],"novelty_at":null,"vendors":["synacor"],"products":["zimbra_collaboration_suite"],"affected":[{"vendor":"synacor","product":"zimbra_collaboration_suite","ranges":["9.0.0","8.8.15"]}]}
