In AD this is implemented by a user attribute delegation_not_allowed (aka not-delegated), which translates to disallow-forwardable. However the Samba AD DC does not do that for S4U2Self and does set the forwardable flag even if the impersonated client has the not-delegated flag set."}],"affected":[{"vendor":"Red Hat","product":"samba","versions":[{"version":"all versions 4.11.x before 4.11.3","status":"affected"},{"version":"all versions 4.10.x before 4.10.11","status":"affected"},{"version":"all versions 4.x.x before 4.9.17","status":"affected"}]}],"references":[{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14870"},{"name":"USN-4217-1","tags":["vendor-advisory"],"url":"https://usn.ubuntu.com/4217-1/"},{"url":"https://security.netapp.com/advisory/ntap-20191210-0002/"},{"url":"https://www.samba.org/samba/security/CVE-2019-14870.html"},{"name":"USN-4217-2","tags":["vendor-advisory"],"url":"https://usn.ubuntu.com/4217-2/"},{"name":"FEDORA-2019-be98a08835","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PJH3ROOFYMOATD2UEPC47P5RPBDTY77E/"},{"url":"https://www.synology.com/security/advisory/Synology_SA_19_40"},{"name":"openSUSE-SU-2019:2700","tags":["vendor-advisory"],"url":"http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00038.html"},{"name":"FEDORA-2019-11dddb785b","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WNKA4YIPV7AZR7KK3GW6L3HKGHSGJZFE/"},{"name":"GLSA-202003-52","tags":["vendor-advisory"],"url":"https://security.gentoo.org/glsa/202003-52"},{"name":"[debian-lts-announce] 20210529 [SECURITY] [DLA 2668-1] samba security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html"},{"name":"[debian-lts-announce] 20221126 [SECURITY] [DLA 3206-1] heimdal security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2022/11/msg00034.html"},{"url":"https://security.netapp.com/advisory/ntap-20230216-0008/"},{"name":"GLSA-202310-06","tags":["vendor-advisory"],"url":"https://security.gentoo.org/glsa/202310-06"}],"metrics":[{"cvssV3_0":{"version":"3.0","vectorString":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE","baseScore":5.4,"baseSeverity":"MEDIUM"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-285","cweId":"CWE-285"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-05T00:26:39.129Z"},"title":"CVE Program Container","references":[{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14870","tags":["x_transferred"]},{"name":"USN-4217-1","tags":["vendor-advisory","x_transferred"],"url":"https://usn.ubuntu.com/4217-1/"},{"url":"https://security.netapp.com/advisory/ntap-20191210-0002/","tags":["x_transferred"]},{"url":"https://www.samba.org/samba/security/CVE-2019-14870.html","tags":["x_transferred"]},{"name":"USN-4217-2","tags":["vendor-advisory","x_transferred"],"url":"https://usn.ubuntu.com/4217-2/"},{"name":"FEDORA-2019-be98a08835","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PJH3ROOFYMOATD2UEPC47P5RPBDTY77E/"},{"url":"https://www.synology.com/security/advisory/Synology_SA_19_40","tags":["x_transferred"]},{"name":"openSUSE-SU-2019:2700","tags":["vendor-advisory","x_transferred"],"url":"http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00038.html"},{"name":"FEDORA-2019-11dddb785b","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WNKA4YIPV7AZR7KK3GW6L3HKGHSGJZFE/"},{"name":"GLSA-202003-52","tags":["vendor-advisory","x_transferred"],"url":"https://security.gentoo.org/glsa/202003-52"},{"name":"[debian-lts-announce] 20210529 [SECURITY] [DLA 2668-1] samba security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html"},{"name":"[debian-lts-announce] 20221126 [SECURITY] [DLA 3206-1] heimdal security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2022/11/msg00034.html"},{"url":"https://security.netapp.com/advisory/ntap-20230216-0008/","tags":["x_transferred"]},{"name":"GLSA-202310-06","tags":["vendor-advisory","x_transferred"],"url":"https://security.gentoo.org/glsa/202310-06"}]}]}}
