CVE-2023-28433 Information

Description

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.
