This flaw allows RODCs and users possessing the GET_CHANGES right to access all attributes, including sensitive secrets and passwords. Even in a default setup, RODC DC accounts, which should only replicate some passwords, can gain access to all domain secrets, including the vital krbtgt, effectively eliminating the RODC / DC distinction. Furthermore, the vulnerability fails to account for error conditions (fail open), like out-of-memory situations, potentially granting access to secret attributes, even under low-privileged attacker influence."}],"affected":[{"product":"samba","vendor":"n/a","versions":[{"version":"4.19.1","status":"unaffected"},{"version":"4.18.8","status":"unaffected"},{"version":"4.17.12","status":"unaffected"}]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 6","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"samba","defaultStatus":"unaffected","cpes":["cpe:/o:redhat:enterprise_linux:6"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 6","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"samba4","defaultStatus":"unaffected","cpes":["cpe:/o:redhat:enterprise_linux:6"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 7","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"samba","defaultStatus":"unaffected","cpes":["cpe:/o:redhat:enterprise_linux:7"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"samba","defaultStatus":"unaffected","cpes":["cpe:/o:redhat:enterprise_linux:8"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"samba","defaultStatus":"unaffected","cpes":["cpe:/o:redhat:enterprise_linux:9"]},{"vendor":"Red Hat","product":"Red Hat Storage 3","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"samba","defaultStatus":"unaffected","cpes":["cpe:/a:redhat:storage:3"]},{"product":"Fedora","vendor":"Fedora","collectionURL":"https://packages.fedoraproject.org/","packageName":"samba","defaultStatus":"affected"}],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2023-4154","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2241883","name":"RHBZ#2241883","tags":["issue-tracking","x_refsource_REDHAT"]},{"url":"https://bugzilla.samba.org/show_bug.cgi?id=15424"},{"url":"https://security.netapp.com/advisory/ntap-20231124-0002/"},{"url":"https://www.samba.org/samba/security/CVE-2023-4154.html"}],"datePublic":"2023-10-10T00:00:00.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-787","description":"Out-of-bounds Write","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-787: Out-of-bounds Write","timeline":[{"lang":"en","time":"2023-10-03T00:00:00.000Z","value":"Reported to Red Hat."},{"lang":"en","time":"2023-10-10T00:00:00.000Z","value":"Made public."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2024-01-23T01:33:49.736Z"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T07:17:12.144Z"},"title":"CVE Program Container","references":[{"url":"https://access.redhat.com/security/cve/CVE-2023-4154","tags":["vdb-entry","x_refsource_REDHAT","x_transferred"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2241883","name":"RHBZ#2241883","tags":["issue-tracking","x_refsource_REDHAT","x_transferred"]},{"url":"https://bugzilla.samba.org/show_bug.cgi?id=15424","tags":["x_transferred"]},{"url":"https://security.netapp.com/advisory/ntap-20231124-0002/","tags":["x_transferred"]},{"url":"https://www.samba.org/samba/security/CVE-2023-4154.html","tags":["x_transferred"]}]}]}}
