Title
SAML authentication vulnerability in Fleet
Summary
Fleet is an open source osquery manager. In Fleet before version 3.5.1, due to issues in Go's standard library XML parsing, a valid SAML response may be mutated by an attacker to modify the trusted document. This can result in allowing unverified logins from a SAML IdP. Users that configure Fleet with SSO login may be vulnerable to this issue. This issue is patched in 3.5.1. The fix was made using https://github.com/mattermost/xml-roundtrip-validator If upgrade to 3.5.1 is not possible, users should disable SSO authentication in Fleet.

In Fleet before version 3.5.1, due to issues in Go\u0027s standard library XML parsing, a valid SAML response may be mutated by an attacker to modify the trusted document. This can result in allowing unverified logins from a SAML IdP. Users that configure Fleet with SSO login may be vulnerable to this issue. This issue is patched in 3.5.1. The fix was made using https://github.com/mattermost/xml-roundtrip-validator If upgrade to 3.5.1 is not possible, users should disable SSO authentication in Fleet.\"},{\"lang\":\"es\",\"value\":\"Fleet es un administrador de osquery de c\u00f3digo abierto.\u0026#xa0;En Fleet versiones anteriores a 3.5.1, debido a problemas en el an\u00e1lisis de XML de la biblioteca est\u00e1ndar de Go, una respuesta v\u00e1lida SAML puede ser mutada por un atacante para modificar el documento confiable.\u0026#xa0;Esto puede resultar en permitir inicios de sesi\u00f3n no verificados desde un IdP SAML.\u0026#xa0;Los usuarios que configuran Fleet con inicio de sesi\u00f3n SSO pueden ser vulnerables a este problema.\u0026#xa0;Este problema est\u00e1 parcheado en la versi\u00f3n 3.5.1.\u0026#xa0;La correcci\u00f3n fue realizada usando https://github.com/mattermost/xml-roundtrip-validator si la actualizaci\u00f3n a la versi\u00f3n 3.5.1 no es posible, los usuarios deben deshabilitar la autenticaci\u00f3n SSO en Fleet\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H\",\"baseScore\":10.0,\"baseSeverity\":\"CRITICAL\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"CHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":3.9,\"impactScore\":6.0},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H\",\"baseScore\":9.8,\"baseSeverity\":\"CRITICAL\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":3.9,\"impactScore\":5.9}],\"cvssMetricV2\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"2.0\",\"vectorString\":\"AV:N/AC:M/Au:N/C:P/I:P/A:P\",\"baseScore\":6.8,\"accessVector\":\"NETWORK\",\"accessComplexity\":\"MEDIUM\",\"authentication\":\"NONE\",\"confidentialityImpact\":\"PARTIAL\",\"integrityImpact\":\"PARTIAL\",\"availabilityImpact\":\"PARTIAL\"},\"baseSeverity\":\"MEDIUM\",\"exploitabilityScore\":8.6,\"impactScore\":6.4,\"acInsufInfo\":false,\"obtainAllPrivilege\":false,\"obtainUserPrivilege\":false,\"obtainOtherPrivilege\":false,\"userInteractionRequired\":false}]},\"weaknesses\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-290\"}]},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-290\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:fleetdm:fleet:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"3.5.1\",\"matchCriteriaId\":\"73A23340-9D58-472D-9ADD-4313F6B9C332\"}]}]}],\"references\":[{\"url\":\"https://github.com/fleetdm/fleet/blob/master/CHANGELOG.md#fleet-351-dec-14-2020\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Release Notes\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/fleetdm/fleet/commit/57812a532e5f749c8e18c6f6a652eca65c083607\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Patch\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/fleetdm/fleet/security/advisories/GHSA-w3wf-cfx3-6gcx\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://github.com/mattermost/xml-roundtrip-validator\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://mattermost.com/blog/coordinated-disclosure-go-xml-vulnerabilities\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Not Applicable\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/fleetdm/fleet/blob/master/CHANGELOG.md#fleet-351-dec-14-2020\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Release Notes\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/fleetdm/fleet/commit/57812a532e5f749c8e18c6f6a652eca65c083607\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/fleetdm/fleet/security/advisories/GHSA-w3wf-cfx3-6gcx\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://github.com/mattermost/xml-roundtrip-validator\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://mattermost.com/blog/coordinated-disclosure-go-xml-vulnerabilities\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Not Applicable\",\"Third Party Advisory\"]}]}}"
