{"id":"ALPINE-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":"2026-03-09T01:19:04.189116Z","published":"2021-05-27T20:15:07.873Z","upstream":["CVE-2020-14387"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-14387"}],"affected":[{"package":{"name":"rsync","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/rsync?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.4-r0"}]}],"versions":["3.0.5-r0","3.0.6-r0","3.0.6-r1","3.0.7-r0","3.0.7-r1","3.0.8-r0","3.0.9-r0","3.0.9-r1","3.1.0-r0","3.1.1-r0","3.1.1-r1","3.1.1-r2","3.1.2-r2","3.1.2-r3","3.1.2-r4","3.1.2-r5","3.1.2-r6","3.1.2-r7","3.1.3-r0","3.1.3-r1","3.1.3-r2","3.1.3-r3","3.2.2-r0","3.2.3-r0","3.2.3-r1","3.2.3-r2","3.2.3-r3","3.2.3-r4","3.2.3-r5"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-14387.json"}},{"package":{"name":"rsync","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/rsync?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.4-r0"}]}],"versions":["3.0.5-r0","3.0.6-r0","3.0.6-r1","3.0.7-r0","3.0.7-r1","3.0.8-r0","3.0.9-r0","3.0.9-r1","3.1.0-r0","3.1.1-r0","3.1.1-r1","3.1.1-r2","3.1.2-r2","3.1.2-r3","3.1.2-r4","3.1.2-r5","3.1.2-r6","3.1.2-r7","3.1.3-r0","3.1.3-r1","3.1.3-r2","3.1.3-r3","3.2.2-r0","3.2.3-r0","3.2.3-r1","3.2.3-r2","3.2.3-r3","3.2.3-r4","3.2.3-r5"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-14387.json"}},{"package":{"name":"rsync","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/rsync?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.4-r0"}]}],"versions":["3.0.5-r0","3.0.6-r0","3.0.6-r1","3.0.7-r0","3.0.7-r1","3.0.8-r0","3.0.9-r0","3.0.9-r1","3.1.0-r0","3.1.1-r0","3.1.1-r1","3.1.1-r2","3.1.2-r2","3.1.2-r3","3.1.2-r4","3.1.2-r5","3.1.2-r6","3.1.2-r7","3.1.3-r0","3.1.3-r1","3.1.3-r2","3.1.3-r3","3.2.2-r0","3.2.3-r0","3.2.3-r1","3.2.3-r2","3.2.3-r3","3.2.3-r4","3.2.3-r5","3.2.3-r6"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-14387.json"}},{"package":{"name":"rsync","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/rsync?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-14387.json"}},{"package":{"name":"rsync","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/rsync?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-14387.json"}},{"package":{"name":"rsync","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/rsync?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-14387.json"}},{"package":{"name":"rsync","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/rsync?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-14387.json"}},{"package":{"name":"rsync","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/rsync?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-14387.json"}},{"package":{"name":"rsync","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/rsync?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-14387.json"}},{"package":{"name":"rsync","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/rsync?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-14387.json"}},{"package":{"name":"rsync","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/rsync?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-14387.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
