{"id":"BIT-minio-2023-28433","summary":"Minio Privilege Escalation on Windows via Path separator manipulation","details":"Minio is a Multi-Cloud Object Storage framework. 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.","aliases":["CVE-2023-28433","GHSA-w23q-4hw3-2pp6"],"modified":"2026-09-08T08:48:13.367913629Z","published":"2024-03-06T10:56:28.094Z","database_specific":{"cpes":["cpe:2.3:a:minio:minio:*:*:*:*:*:*:*:*"],"severity":"High"},"references":[{"type":"FIX","url":"https://github.com/minio/minio/commit/8d6558b23649f613414c8527b58973fbdfa4d1b8"},{"type":"FIX","url":"https://github.com/minio/minio/commit/b3c54ec81e0a06392abfb3a1ffcdc80c6fbf6ebc"},{"type":"ARTICLE","url":"https://github.com/minio/minio/releases/tag/RELEASE.2023-03-20T20-16-18Z"},{"type":"ADVISORY","url":"https://github.com/minio/minio/security/advisories/GHSA-w23q-4hw3-2pp6"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-28433"}],"affected":[{"package":{"name":"minio","ecosystem":"Bitnami","purl":"pkg:bitnami/minio"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2023.03.20"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/minio/BIT-minio-2023-28433.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}],"schema_version":"1.9.0"}
