Vulnerability from cvelistv5

Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
A design flaw was found in Samba's DirSync control implementation, which exposes passwords and secrets in Active Directory to privileged users and Read-Only Domain Controllers (RODCs). 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.

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\"]}]}}",
