Vulnerability from cvelistv5
Published

Modified
2024-08-04 19:19
Severity ?
6.5 (Medium) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N
Summary
A vulnerability was found in keycloak before 6.0.2. The X.509 authenticator supports the verification of client certificates through the CRL, where the CRL list can be obtained from the URL provided in the certificate itself (CDP) or through the separately configured path. The CRL are often available over the network through unsecured protocols ('http' or 'ldap') and hence the caller should verify the signature and possibly the certification path. Keycloak currently doesn't validate signatures on CRL, which can result in a possibility of various attacks like man-in-the-middle.

El autenticador X.509 admite la comprobación de certificados de cliente por medio de la CRL, donde la lista CRL se puede obtener de la URL proporcionada en el certificado (CDP) o por medio de la path configurada por separado. Los CRL frecuentemente están disponibles por medio de la red mediante protocolos no seguros ('http' o 'ldap') y, por lo tanto, la persona que llama debe verificar la firma y posiblemente la path de certificación. Keycloak actualmente no comprueba las firmas en CRL, lo que resulta en la posibilidad de varios ataques de tipo hombre en el medio (man-in-the-middle).\"}],\"metrics\":{\"cvssMetricV30\":[{\"source\":\"secalert@redhat.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.0\",\"vectorString\":\"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N\",\"baseScore\":6.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"LOW\",\"integrityImpact\":\"LOW\",\"availabilityImpact\":\"NONE\"},\"exploitabilityScore\":3.9,\"impactScore\":2.5},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.0\",\"vectorString\":\"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N\",\"baseScore\":4.8,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"LOW\",\"integrityImpact\":\"LOW\",\"availabilityImpact\":\"NONE\"},\"exploitabilityScore\":2.2,\"impactScore\":2.5}],\"cvssMetricV2\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"2.0\",\"vectorString\":\"AV:N/AC:M/Au:N/C:P/I:P/A:N\",\"baseScore\":5.8,\"accessVector\":\"NETWORK\",\"accessComplexity\":\"MEDIUM\",\"authentication\":\"NONE\",\"confidentialityImpact\":\"PARTIAL\",\"integrityImpact\":\"PARTIAL\",\"availabilityImpact\":\"NONE\"},\"baseSeverity\":\"MEDIUM\",\"exploitabilityScore\":8.6,\"impactScore\":4.9,\"acInsufInfo\":false,\"obtainAllPrivilege\":false,\"obtainUserPrivilege\":false,\"obtainOtherPrivilege\":false,\"userInteractionRequired\":false}]},\"weaknesses\":[{\"source\":\"secalert@redhat.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-295\"},{\"lang\":\"en\",\"value\":\"CWE-345\"}]},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-295\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:redhat:keycloak:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"6.0.2\",\"matchCriteriaId\":\"D7096C1E-0B43-4458-83D6-1F94061279E5\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:redhat:single_sign-on:7.3:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"E939A0E0-3437-459E-9FAB-FE42811B1D32\"}]}]}],\"references\":[{\"url\":\"http://www.securityfocus.com/bid/108748\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Third Party Advisory\",\"VDB Entry\"]},{\"url\":\"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3875\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Issue Tracking\",\"Patch\",\"Vendor Advisory\"]},{\"url\":\"http://www.securityfocus.com/bid/108748\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\",\"VDB Entry\"]},{\"url\":\"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3875\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Issue Tracking\",\"Patch\",\"Vendor Advisory\"]}]}}",
