{"id":"CVE-2023-28433","published":"2023-03-22T20:33:43Z","modified":"2025-02-25T14:51:18Z","title":"Minio Privilege Escalation on Windows via Path separator manipulation","vendor":"minio","product":"minio","tier":"tail","description":{"text":"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.","provenance":"source","from":"CVE.org"},"cvss":{"score":8.8,"severity":"HIGH","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.00981,"percentile":0.62138,"provenance":"source"},"cwes":[{"id":"CWE-668","name":"Exposure of Resource to Wrong Sphere"}],"references":[{"url":"https://github.com/minio/minio/security/advisories/GHSA-w23q-4hw3-2pp6","tags":["x_refsource_CONFIRM"]},{"url":"https://github.com/minio/minio/commit/8d6558b23649f613414c8527b58973fbdfa4d1b8","tags":["x_refsource_MISC"]},{"url":"https://github.com/minio/minio/commit/b3c54ec81e0a06392abfb3a1ffcdc80c6fbf6ebc","tags":["x_refsource_MISC"]},{"url":"https://github.com/minio/minio/releases/tag/RELEASE.2023-03-20T20-16-18Z","tags":["x_refsource_MISC"]}],"priority":{"score":18.6,"factors":[{"name":"EPSS percentile","points":12.43},{"name":"CVSS severity","points":6.16}]},"vendorSlug":"minio","affectedVersions":[{"vendor":"minio","product":"minio","versions":["< RELEASE.2023-03-20T20-16-18Z"]}],"affected":[{"ecosystem":"Go","package":"github.com/minio/minio","vulnerableRanges":["<0.0.0-202303200735"],"patched":["0.0.0-202303200735"],"from":["GHSA-w23q-4hw3-2pp6"],"provenance":"source"}],"euvd":{"id":"EUVD-2023-2606","exploited":false,"provenance":"source"},"lineage":{"packageHistory":[{"cve":"CVE-2023-28434","published":"2023-03-22","fixed":"0.0.0-202303200415","kev":true,"link":{"from":"CVE-2023-28434","to":"CVE-2023-28433","relation":"successor","confidence":"medium","kind":"sequence","orderedBy":"description","evidence":[{"kind":"version-step","provenance":"source","package":"Go:github.com/minio/minio","fromFixed":"0.0.0-202303200415","toFixed":"0.0.0-202303200735","daysApart":0},{"kind":"similar","provenance":"machine","score":0.4,"basis":"same product + description similarity"}]}},{"cve":"CVE-2023-28433","published":"2023-03-22","fixed":"0.0.0-202303200735","kev":false},{"cve":"CVE-2024-24747","published":"2024-01-31","fixed":"0.0.0-20240131185645-0ae4915a9391","kev":false,"link":{"from":"CVE-2023-28433","to":"CVE-2024-24747","relation":"successor","confidence":"low","kind":"sequence","evidence":[{"kind":"version-step","provenance":"source","package":"Go:github.com/minio/minio","fromFixed":"0.0.0-202303200735","toFixed":"0.0.0-20240131185645-0ae4915a9391","daysApart":315}]}},{"cve":"CVE-2024-36107","published":"2024-05-28","fixed":"0.0.0-20240527191746-e0fe7cc39172","kev":false},{"cve":"CVE-2024-55949","published":"2024-12-16","fixed":"0.0.0-20241213221912-68b004a48f41","kev":false}],"package":"Go:github.com/minio/minio"}}
