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." }, { "lang": "es", "value": "Se encontr\u00f3 una falla de dise\u00f1o en la implementaci\u00f3n del control DirSync de Samba, que expone contrase\u00f1as y secretos en Active Directory a usuarios privilegiados y Controladores de Dominio de Solo Lectura (RODC). Esta falla permite a los RODC y a los usuarios que poseen el derecho GET_CHANGES acceder a todos los atributos, incluidos secretos y contrase\u00f1as confidenciales. Incluso en una configuraci\u00f3n predeterminada, las cuentas RODC DC, que solo deber\u00edan replicar algunas contrase\u00f1as, pueden obtener acceso a todos los secretos del dominio, incluido el vital krbtgt, eliminando efectivamente la distinci\u00f3n RODC/DC. Adem\u00e1s, la vulnerabilidad no tiene en cuenta las condiciones de error (fallo de apertura), como situaciones de falta de memoria, lo que potencialmente otorga acceso a atributos secretos, incluso bajo la influencia de un atacante con pocos privilegios." } ], "metrics": { "cvssMetricV31": [ { "source": "nvd@nist.gov", "type": "Primary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "NONE", "availabilityImpact": "NONE", "baseScore": 6.5, "baseSeverity": "MEDIUM" }, "exploitabilityScore": 2.8, "impactScore": 3.6 }, { "source": "secalert@redhat.com", "type": "Secondary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H", "attackVector": "NETWORK", "attackComplexity": "HIGH", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 7.5, "baseSeverity": "HIGH" }, "exploitabilityScore": 1.6, "impactScore": 5.9 } ] }, "weaknesses": [ { "source": "nvd@nist.gov", "type": "Primary", "description": [ { "lang": "en", "value": "CWE-787" } ] }, { "source": "secalert@redhat.com", "type": "Secondary", "description": [ { "lang": "en", "value": "CWE-200" } ] } ], "configurations": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:a:samba:samba:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.0.0", "versionEndExcluding": "4.17.12", "matchCriteriaId": "F1CC08E7-E96D-4475-ACB6-22CDF280913E" }, { "vulnerable": true, "criteria": "cpe:2.3:a:samba:samba:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.18.0", "versionEndExcluding": "4.18.8", "matchCriteriaId": "8A33312F-1523-4647-83DA-6DD6231906F9" }, { "vulnerable": true, "criteria": "cpe:2.3:a:samba:samba:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.19.0", "versionEndExcluding": "4.19.1", "matchCriteriaId": "DE496104-DDB5-4709-8026-C83E99B0C865" } ] } ] } ], "references": [ { "url": "https://access.redhat.com/security/cve/CVE-2023-4154", "source": "secalert@redhat.com", "tags": [ "Third Party Advisory" ] }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2241883", "source": "secalert@redhat.com", "tags": [ "Issue Tracking" ] }, { "url": "https://bugzilla.samba.org/show_bug.cgi?id=15424", "source": "secalert@redhat.com", "tags": [ "Issue Tracking", "Patch" ] }, { "url": "https://www.samba.org/samba/security/CVE-2023-4154.html", "source": "secalert@redhat.com", "tags": [ "Vendor Advisory" ] } ] }
