Any authenticated user can create an EC2 credential for themselves for a project that they have a specified role on, and then perform an update to the credential user and project, allowing them to masquerade as another user. This potentially allows a malicious user to act as the admin on a project another user has the admin role on, which can effectively grant that user global admin privileges." }, { "lang": "es", "value": "Se detect\u00f3 un problema en OpenStack Keystone versiones anteriores a 15.0.1 y 16.0.0. Cualquier usuario autenticado puede crear una credencial EC2 para s\u00ed mismo para un proyecto en el que posee un rol espec\u00edfico, y luego llevar a cabo una actualizaci\u00f3n para el usuario y el proyecto de la credencial, permiti\u00e9ndole hacerse pasar por otro usuario. Esto permite potencialmente a un usuario malicioso actuar como el administrador en un proyecto en el que otro usuario presenta la funci\u00f3n de administrador, que puede otorgarle efectivamente a ese usuario privilegios de administrador global." } ], "metrics": { "cvssMetricV31": [ { "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:H/A:H", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 8.8, "baseSeverity": "HIGH" }, "exploitabilityScore": 2.8, "impactScore": 5.9 } ], "cvssMetricV2": [ { "source": "nvd@nist.gov", "type": "Primary", "cvssData": { "version": "2.0", "vectorString": "AV:N/AC:L/Au:S/C:P/I:P/A:P", "accessVector": "NETWORK", "accessComplexity": "LOW", "authentication": "SINGLE", "confidentialityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "availabilityImpact": "PARTIAL", "baseScore": 6.5 }, "baseSeverity": "MEDIUM", "exploitabilityScore": 8.0, "impactScore": 6.4, "acInsufInfo": false, "obtainAllPrivilege": false, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false } ] }, "weaknesses": [ { "source": "nvd@nist.gov", "type": "Primary", "description": [ { "lang": "en", "value": "CWE-863" } ] } ], "configurations": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:a:openstack:keystone:*:*:*:*:*:*:*:*", "versionEndExcluding": "15.0.1", "matchCriteriaId": "04CBF40B-EE82-4FB1-8B57-502419051BA9" }, { "vulnerable": true, "criteria": "cpe:2.3:a:openstack:keystone:16.0.0:*:*:*:*:*:*:*", "matchCriteriaId": "71945B91-B12D-4EF4-AE03-91592D434125" } ] } ] }, { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:canonical:ubuntu_linux:18.04:*:*:*:lts:*:*:*", "matchCriteriaId": "23A7C53F-B80F-4E6A-AFA9-58EEA84BE11D" } ] } ] } ], "references": [ { "url": "http://www.openwall.com/lists/oss-security/2020/05/07/2", "source": "cve@mitre.org", "tags": [ "Mailing List", "Third Party Advisory" ] }, { "url": "https://bugs.launchpad.net/keystone/+bug/1872733", "source": "cve@mitre.org", "tags": [ "Patch", "Third Party Advisory" ] }, { "url": "https://lists.apache.org/thread.html/re237267da268c690df5e1c6ea6a38a7fc11617725e8049490f58a6fa%40%3Ccommits.druid.apache.org%3E", "source": "cve@mitre.org" }, { "url": "https://lists.apache.org/thread.html/re4ffc55cd2f1b55a26e07c83b3c22c3fe4bae6054d000a57fb48d8c2%40%3Ccommits.druid.apache.org%3E", "source": "cve@mitre.org" }, { "url": "https://security.openstack.org/ossa/OSSA-2020-004.html", "source": "cve@mitre.org", "tags": [ "Vendor Advisory" ] }, { "url": "https://usn.ubuntu.com/4480-1/", "source": "cve@mitre.org", "tags": [ "Third Party Advisory" ] }, { "url": "https://www.openwall.com/lists/oss-security/2020/05/06/5", "source": "cve@mitre.org", "tags": [ "Mailing List", "Third Party Advisory" ] } ] }
