{"id":"GHSA-4427-7f3w-mqv6","summary":"OpenStack Keystone V3 /credentials endpoint policy logic allows to change credentials owner or target project ID","details":"An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. 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.","aliases":["CVE-2020-12691","PYSEC-2020-55"],"modified":"2024-09-27T18:31:51.700085Z","published":"2022-05-24T17:17:23Z","database_specific":{"nvd_published_at":"2020-05-07T00:15:00Z","cwe_ids":["CWE-311","CWE-863"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2024-04-29T10:24:16Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-12691"},{"type":"WEB","url":"https://github.com/openstack/keystone/commit/37e9907a176dad6843819b1bec4946c3aecc4548"},{"type":"WEB","url":"https://github.com/openstack/keystone/commit/40cbb7bebd50276412daa1981ff5a7c7b3b899a5"},{"type":"WEB","url":"https://github.com/openstack/keystone/commit/95b2bbeab113d9f04d1c81f7f1b48bf692bce979"},{"type":"WEB","url":"https://bugs.launchpad.net/keystone/+bug/1872733"},{"type":"PACKAGE","url":"https://github.com/openstack/keystone"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/keystone/PYSEC-2020-55.yaml"},{"type":"WEB","url":"https://lists.apache.org/thread.html/re237267da268c690df5e1c6ea6a38a7fc11617725e8049490f58a6fa@%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/re4ffc55cd2f1b55a26e07c83b3c22c3fe4bae6054d000a57fb48d8c2@%3Ccommits.druid.apache.org%3E"},{"type":"WEB","url":"https://security.openstack.org/ossa/OSSA-2020-004.html"},{"type":"WEB","url":"https://usn.ubuntu.com/4480-1"},{"type":"WEB","url":"https://www.openwall.com/lists/oss-security/2020/05/06/5"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2020/05/07/2"}],"affected":[{"package":{"name":"keystone","ecosystem":"PyPI","purl":"pkg:pypi/keystone"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"15.0.1"}]}],"versions":["12.0.2","12.0.3","13.0.2","13.0.3","13.0.4","14.0.0","14.0.1","14.1.0","14.2.0","15.0.0","15.0.0.0rc1","15.0.0.0rc2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-4427-7f3w-mqv6/GHSA-4427-7f3w-mqv6.json"}},{"package":{"name":"keystone","ecosystem":"PyPI","purl":"pkg:pypi/keystone"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"16.0.0"},{"fixed":"16.0.1"}]}],"versions":["16.0.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-4427-7f3w-mqv6/GHSA-4427-7f3w-mqv6.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
