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." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "Out-of-bounds Write", "cweId": "CWE-787" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "n/a", "product": { "product_data": [ { "product_name": "samba", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "4.19.1", "status": "unaffected" }, { "version": "4.18.8", "status": "unaffected" }, { "version": "4.17.12", "status": "unaffected" } ] } } ] } } ] } }, { "vendor_name": "Red Hat", "product": { "product_data": [ { "product_name": "Red Hat Enterprise Linux 6", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unaffected" } }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unaffected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 7", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unaffected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 8", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unaffected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 9", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unaffected" } } ] } }, { "product_name": "Red Hat Storage 3", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unaffected" } } ] } } ] } }, { "vendor_name": "Fedora", "product": { "product_data": [ { "product_name": "Fedora", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://access.redhat.com/security/cve/CVE-2023-4154", "refsource": "MISC", "name": "https://access.redhat.com/security/cve/CVE-2023-4154" }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2241883", "refsource": "MISC", "name": "https://bugzilla.redhat.com/show_bug.cgi?id=2241883" }, { "url": "https://bugzilla.samba.org/show_bug.cgi?id=15424", "refsource": "MISC", "name": "https://bugzilla.samba.org/show_bug.cgi?id=15424" }, { "url": "https://security.netapp.com/advisory/ntap-20231124-0002/", "refsource": "MISC", "name": "https://security.netapp.com/advisory/ntap-20231124-0002/" }, { "url": "https://www.samba.org/samba/security/CVE-2023-4154.html", "refsource": "MISC", "name": "https://www.samba.org/samba/security/CVE-2023-4154.html" } ] }, "impact": { "cvss": [ { "attackComplexity": "HIGH", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 7.5, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H", "version": "3.1" } ] } }
