All users on Windows prior to version RELEASE.2023-03-20T20-16-18Z are impacted. MinIO fails to filter the `\\` character, which allows for arbitrary object placement across buckets. As a result, a user with low privileges, such as an access key, service account, or STS credential, which only has permission to `PutObject` in a specific bucket, can create an admin user. This issue is patched in RELEASE.2023-03-20T20-16-18Z. There are no known workarounds.","state":0,"publishedAt":"2023-03-22T20:33:43.452+00:00","modifiedAt":"2025-02-25T14:51:18.769+00:00","affected":[{"ecosystem":"Vendor product","name":"minio","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"minio\",\n                    \"product\": \"minio\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< RELEASE.2023-03-20T20-16-18Z\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/minio/minio/security/advisories/GHSA-w23q-4hw3-2pp6","https://github.com/minio/minio/commit/8d6558b23649f613414c8527b58973fbdfa4d1b8","https://github.com/minio/minio/commit/b3c54ec81e0a06392abfb3a1ffcdc80c6fbf6ebc","https://github.com/minio/minio/releases/tag/RELEASE.2023-03-20T20-16-18Z"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2023-28433","license":"CVE Program Terms of Use","key":"cve-program:CVE-2023-28433","identifiers":["CVE-2023-28433"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
