{"id":"CVE-2020-14387","details":"A flaw was found in rsync in versions since 3.2.0pre1. Rsync improperly validates certificate with host mismatch vulnerability. A remote, unauthenticated attacker could exploit the flaw by performing a man-in-the-middle attack using a valid certificate for another hostname which could compromise confidentiality and integrity of data transmitted using rsync-ssl. The highest threat from this vulnerability is to data confidentiality and integrity. This flaw affects rsync versions before 3.2.4.","modified":"2026-08-27T08:13:49.996321Z","published":"2021-05-27T20:15:07.873Z","related":["SUSE-RU-2023:3370-1","openSUSE-SU-2024:11308-1"],"references":[{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1875549"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.samba.org/rsync.git/","events":[{"introduced":"a8fc8fc2d22ba7243b96decb91c586682a05e4a1"},{"fixed":"0ac7ebceef70417355f25daf9e2fd94e84c49749"},{"introduced":"c225330aaf9d6032a79317bda1bf669e90ac7212"},{"last_affected":"0b2d5fe4940211ba25a89f18a9889b9ab55d38ef"}],"database_specific":{"cpe":["cpe:2.3:a:samba:rsync:*:*:*:*:*:*:*:*","cpe:2.3:a:samba:rsync:3.2.0:-:*:*:*:*:*:*","cpe:2.3:a:samba:rsync:3.2.0:pre1:*:*:*:*:*:*","cpe:2.3:a:samba:rsync:3.2.0:pre2:*:*:*:*:*:*","cpe:2.3:a:samba:rsync:3.2.0:pre3:*:*:*:*:*:*"],"extracted_events":[{"introduced":"3.2.1"},{"fixed":"3.2.4"},{"introduced":"3.2.0-NA"},{"last_affected":"3.2.0-NA"},{"introduced":"3.2.0-pre1"},{"last_affected":"3.2.0-pre1"},{"introduced":"3.2.0-pre2"},{"last_affected":"3.2.0-pre2"},{"introduced":"3.2.0-pre3"},{"last_affected":"3.2.0-pre3"}],"source":["CPE_RANGE","CPE_STRING"]}}],"versions":["3.2.0-NA","3.2.0-pre1","3.2.0-pre2","3.2.0-pre3","v3.2.4pre4","v3.2.4pre3","v3.2.4pre2","v3.2.4pre1","v3.2.3","v3.2.3pre1","v3.2.2","v3.2.2pre3","v3.2.2pre2","v3.2.2pre1","v3.2.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-14387.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/RsyncProject/rsync","events":[{"introduced":"a8fc8fc2d22ba7243b96decb91c586682a05e4a1"},{"fixed":"0ac7ebceef70417355f25daf9e2fd94e84c49749"},{"introduced":"c225330aaf9d6032a79317bda1bf669e90ac7212"},{"last_affected":"0b2d5fe4940211ba25a89f18a9889b9ab55d38ef"}],"database_specific":{"cpe":["cpe:2.3:a:samba:rsync:*:*:*:*:*:*:*:*","cpe:2.3:a:samba:rsync:3.2.0:-:*:*:*:*:*:*","cpe:2.3:a:samba:rsync:3.2.0:pre1:*:*:*:*:*:*","cpe:2.3:a:samba:rsync:3.2.0:pre2:*:*:*:*:*:*","cpe:2.3:a:samba:rsync:3.2.0:pre3:*:*:*:*:*:*"],"extracted_events":[{"introduced":"3.2.1"},{"fixed":"3.2.4"},{"introduced":"3.2.0-NA"},{"last_affected":"3.2.0-NA"},{"introduced":"3.2.0-pre1"},{"last_affected":"3.2.0-pre1"},{"introduced":"3.2.0-pre2"},{"last_affected":"3.2.0-pre2"},{"introduced":"3.2.0-pre3"},{"last_affected":"3.2.0-pre3"}],"source":["CPE_RANGE","CPE_STRING"]}}],"versions":["3.2.0-NA","3.2.0-pre1","3.2.0-pre2","3.2.0-pre3","v3.2.4pre4","v3.2.4pre3","v3.2.4pre2","v3.2.4pre1","v3.2.3","v3.2.3pre1","v3.2.2","v3.2.2pre3","v3.2.2pre2","v3.2.2pre1","v3.2.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-14387.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/rsyncproject/rsync","events":[{"introduced":"a8fc8fc2d22ba7243b96decb91c586682a05e4a1"},{"fixed":"0ac7ebceef70417355f25daf9e2fd94e84c49749"},{"introduced":"c225330aaf9d6032a79317bda1bf669e90ac7212"},{"last_affected":"0b2d5fe4940211ba25a89f18a9889b9ab55d38ef"}],"database_specific":{"cpe":["cpe:2.3:a:samba:rsync:*:*:*:*:*:*:*:*","cpe:2.3:a:samba:rsync:3.2.0:-:*:*:*:*:*:*","cpe:2.3:a:samba:rsync:3.2.0:pre1:*:*:*:*:*:*","cpe:2.3:a:samba:rsync:3.2.0:pre2:*:*:*:*:*:*","cpe:2.3:a:samba:rsync:3.2.0:pre3:*:*:*:*:*:*"],"extracted_events":[{"introduced":"3.2.1"},{"fixed":"3.2.4"},{"introduced":"3.2.0-NA"},{"last_affected":"3.2.0-NA"},{"introduced":"3.2.0-pre1"},{"last_affected":"3.2.0-pre1"},{"introduced":"3.2.0-pre2"},{"last_affected":"3.2.0-pre2"},{"introduced":"3.2.0-pre3"},{"last_affected":"3.2.0-pre3"}],"source":["CPE_RANGE","CPE_STRING"]}}],"versions":["3.2.0-NA","3.2.0-pre1","3.2.0-pre2","3.2.0-pre3","v3.2.4pre4","v3.2.4pre3","v3.2.4pre2","v3.2.4pre1","v3.2.3","v3.2.3pre1","v3.2.2","v3.2.2pre3","v3.2.2pre2","v3.2.2pre1","v3.2.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-14387.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
