{"id":"CVE-2022-41352","url":"https://www.cyber-defence.io/tools/cve/CVE-2022-41352","generatedAt":"2026-10-31T12:55:24.023Z","title":"Synacor Zimbra Collaboration Suite (ZCS) Arbitrary File Upload Vulnerability","description":"An issue was discovered in Zimbra Collaboration (ZCS) 8.8.15 and 9.0. 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.","published":"2022-09-26T02:15:11.000Z","lastModified":"2026-09-10T04:17:37.000Z","status":"Analyzed","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-22"],"affected":["synacor/zimbra collaboration suite"],"epss":{"score":0.95478,"percentile":0.99869,"date":"2026-10-30","history":[]},"kev":{"listed":true,"dateAdded":"2022-10-20","dueDate":"2022-11-10","knownRansomwareCampaignUse":"Known","notes":"Apply updates per vendor instructions.\nhttps://wiki.zimbra.com/wiki/Security_Center;  https://nvd.nist.gov/vuln/detail/CVE-2022-41352"},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"Known to be exploited in the wild (CISA KEV, CISA remediation deadline 10 November 2022).
