Vulnerability from cvelistv5

Severity ?
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
A flaw was found in Samba. It is susceptible to a vulnerability where multiple incompatible RPC listeners can be initiated, causing disruptions in the AD DC service. When Samba's RPC server experiences a high load or unresponsiveness, servers intended for non-AD DC purposes (for example, NT4-emulation "classic DCs") can erroneously start and compete for the same unix domain sockets. This issue leads to partial query responses from the AD DC, causing issues such as "The procedure number is out of range" when using tools like Active Directory Users. This flaw allows an attacker to disrupt AD DC services.

Cuando el servidor RPC de Samba experimenta una carga alta o no responde, los servidores destinados a fines que no son AD DC (por ejemplo, los \\\"DC clásicos\\\" de NT4-emulation) pueden iniciarse erróneamente y competir por los mismos sockets de dominio Unix. Este problema genera respuestas de consulta parciales del AD DC, lo que provoca problemas como \\\"El número de procedimiento está fuera de rango\\\" cuando se utilizan herramientas como Usuarios de Active Directory. Esta falla permite a un atacante interrumpir los servicios de AD DC.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"secalert@redhat.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":6.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":2.8,\"impactScore\":3.6},{\"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:N/I:N/A:H\",\"baseScore\":6.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":2.8,\"impactScore\":3.6}]},\"weaknesses\":[{\"source\":\"secalert@redhat.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-400\"}]},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"NVD-CWE-noinfo\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:samba:samba:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"4.17.12\",\"matchCriteriaId\":\"1C9913F9-D46D-4CE3-AA78-E50D32779971\"},{\"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\"}]}]},{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:fedoraproject:fedora:39:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"B8EDB836-4E6A-4B71-B9B2-AA3E03E0F646\"}]}]}],\"references\":[{\"url\":\"https://access.redhat.com/security/cve/CVE-2023-42670\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://bugzilla.redhat.com/show_bug.cgi?id=2241885\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Issue Tracking\"]},{\"url\":\"https://bugzilla.samba.org/show_bug.cgi?id=15473\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Issue Tracking\"]},{\"url\":\"https://www.samba.org/samba/security/CVE-2023-42670.html\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"https://access.redhat.com/security/cve/CVE-2023-42670\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://bugzilla.redhat.com/show_bug.cgi?id=2241885\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Issue Tracking\"]},{\"url\":\"https://bugzilla.samba.org/show_bug.cgi?id=15473\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Issue Tracking\"]},{\"url\":\"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/ZUMVALLFFDFC53JZMUWA6HPD7HUGAP5I/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://security.netapp.com/advisory/ntap-20231124-0002/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://www.samba.org/samba/security/CVE-2023-42670.html\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Vendor Advisory\"]}]}}",
