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 encontró una falla de diseño en la implementación del control DirSync de Samba, que expone contraseñas 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 contraseñas confidenciales. Incluso en una configuración predeterminada, las cuentas RODC DC, que solo deberían replicar algunas contraseñas, pueden obtener acceso a todos los secretos del dominio, incluido el vital krbtgt, eliminando efectivamente la distinción RODC/DC. Además, 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":"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","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.6,"impactScore":5.9},{"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","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":3.6}]},"weaknesses":[{"source":"secalert@redhat.com","type":"Secondary","description":[{"lang":"en","value":"CWE-787"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-787"}]}],"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://security.netapp.com/advisory/ntap-20231124-0002/","source":"secalert@redhat.com"},{"url":"https://www.samba.org/samba/security/CVE-2023-4154.html","source":"secalert@redhat.com","tags":["Vendor Advisory"]},{"url":"https://access.redhat.com/security/cve/CVE-2023-4154","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2241883","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Issue Tracking"]},{"url":"https://bugzilla.samba.org/show_bug.cgi?id=15424","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Issue Tracking","Patch"]},{"url":"https://security.netapp.com/advisory/ntap-20231124-0002/","source":"af854a3a-2127-422b-91ae-364da2661108"},{"url":"https://www.samba.org/samba/security/CVE-2023-4154.html","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
