Summary
Grafana is an open-source platform for monitoring and observability. In versions 5.3 until 9.0.3, 8.5.9, 8.4.10, and 8.3.10, it is possible for a malicious user who has authorization to log into a Grafana instance via a configured OAuth IdP which provides a login name to take over the account of another user in that Grafana instance. This can occur when the malicious user is authorized to log in to Grafana via OAuth, the malicious user's external user id is not already associated with an account in Grafana, the malicious user's email address is not already associated with an account in Grafana, and the malicious user knows the Grafana username of the target user. If these conditions are met, the malicious user can set their username in the OAuth provider to that of the target user, then go through the OAuth flow to log in to Grafana. Due to the way that external and internal user accounts are linked together during login, if the conditions above are all met then the malicious user will be able to log in to the target user's Grafana account. Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10 contain a patch for this issue. As a workaround, concerned users can disable OAuth login to their Grafana instance, or ensure that all users authorized to log in via OAuth have a corresponding user account in Grafana linked to their email address.

In versions 5.3 until 9.0.3, 8.5.9, 8.4.10, and 8.3.10, it is possible for a malicious user who has authorization to log into a Grafana instance via a configured OAuth IdP which provides a login name to take over the account of another user in that Grafana instance. This can occur when the malicious user is authorized to log in to Grafana via OAuth, the malicious user's external user id is not already associated with an account in Grafana, the malicious user's email address is not already associated with an account in Grafana, and the malicious user knows the Grafana username of the target user. If these conditions are met, the malicious user can set their username in the OAuth provider to that of the target user, then go through the OAuth flow to log in to Grafana. Due to the way that external and internal user accounts are linked together during login, if the conditions above are all met then the malicious user will be able to log in to the target user's Grafana account. Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10 contain a patch for this issue. As a workaround, concerned users can disable OAuth login to their Grafana instance, or ensure that all users authorized to log in via OAuth have a corresponding user account in Grafana linked to their email address.\"},{\"lang\":\"es\",\"value\":\"Grafana es una plataforma de código abierto para la monitorización y la observación. En versiones 5.3 hasta 9.0.3, 8.5.9, 8.4.10 y 8.3.10, es posible que un usuario malicioso que tenga autorización para iniciar sesión en una instancia de Grafana por medio de un IdP de OAuth configurado que proporcione un nombre de inicio de sesión, tome la cuenta de otro usuario en esa instancia de Grafana. Esto puede ocurrir cuando el usuario malicioso está autorizado a iniciar sesión en Grafana por medio de OAuth, el id de usuario externo del usuario malicioso no está ya asociado a una cuenta en Grafana, la dirección de correo electrónico del usuario malicioso no está ya asociada a una cuenta en Grafana, y el usuario malicioso conoce el nombre de usuario de Grafana del usuario objetivo. Si son cumplidas estas condiciones, el usuario malicioso puede establecer su nombre de usuario en el proveedor OAuth al del usuario objetivo, y luego pasar por el flujo OAuth para iniciar sesión en Grafana. Debido a la forma en que las cuentas de usuario externas e internas están vinculadas durante el inicio de sesión, si las condiciones anteriores son cumplidas, el usuario malicioso podrá iniciar sesión en la cuenta de Grafana del usuario objetivo. Las versiones 9.0.3, 8.5.9, 8.4.10 y 8.3.10 contienen un parche para este problema. Como mitigación, los usuarios afectados pueden deshabilitar el inicio de sesión de OAuth en su instancia de Grafana, o asegurarse de que todos los usuarios autorizados a iniciar sesión por medio de OAuth presentan una cuenta de usuario correspondiente en Grafana vinculada a su dirección de correo electrónico\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"security-advisories@github.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:L\",\"baseScore\":7.1,\"baseSeverity\":\"HIGH\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"LOW\"},\"exploitabilityScore\":1.6,\"impactScore\":5.5},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"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}]},\"weaknesses\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-863\"}]},{\"source\":\"nvd@nist.gov\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-863\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:grafana:grafana:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.3.0\",\"versionEndExcluding\":\"8.3.10\",\"matchCriteriaId\":\"84AA9DAD-BDBD-402E-B680-250A7295B57E\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:grafana:grafana:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"8.4.0\",\"versionEndExcluding\":\"8.4.10\",\"matchCriteriaId\":\"A5136FB0-D7F8-4BDD-9C70-CB2648065A1F\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:grafana:grafana:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"8.5.0\",\"versionEndExcluding\":\"8.5.9\",\"matchCriteriaId\":\"7C2FAADE-D9EA-431C-ACFA-9F846F14B5A2\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:grafana:grafana:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"9.0.0\",\"versionEndExcluding\":\"9.0.3\",\"matchCriteriaId\":\"A29E8B3E-D3A9-49A4-ABCD-4E87F8B527DD\"}]}]},{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:netapp:e-series_performance_analyzer:-:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"24B8DB06-590A-4008-B0AB-FCD1401C77C6\"}]}]}],\"references\":[{\"url\":\"https://github.com/grafana/grafana/security/advisories/GHSA-mx47-6497-3fv2\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Release Notes\",\"Third Party Advisory\"]},{\"url\":\"https://grafana.com/docs/grafana/next/release-notes/release-notes-8-4-10/\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Release Notes\",\"Vendor Advisory\"]},{\"url\":\"https://grafana.com/docs/grafana/next/release-notes/release-notes-8-5-9/\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Release Notes\",\"Vendor Advisory\"]},{\"url\":\"https://grafana.com/docs/grafana/next/release-notes/release-notes-9-0-3/\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Release Notes\",\"Vendor Advisory\"]},{\"url\":\"https://security.netapp.com/advisory/ntap-20220901-0010/\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://github.com/grafana/grafana/security/advisories/GHSA-mx47-6497-3fv2\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Release Notes\",\"Third Party Advisory\"]},{\"url\":\"https://grafana.com/docs/grafana/next/release-notes/release-notes-8-4-10/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Release Notes\",\"Vendor Advisory\"]},{\"url\":\"https://grafana.com/docs/grafana/next/release-notes/release-notes-8-5-9/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Release Notes\",\"Vendor Advisory\"]},{\"url\":\"https://grafana.com/docs/grafana/next/release-notes/release-notes-9-0-3/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Release Notes\",\"Vendor Advisory\"]},{\"url\":\"https://security.netapp.com/advisory/ntap-20220901-0010/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\"]}]}}",
