Overview
github.com/minio/minio/cmd is an open source object storage server compatible with Amazon S3 APIs.
Affected versions of this package are vulnerable to Privilege Escalation due to improper filtering 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.
Note:
This vulnerability impacts only Windows users.
The vulnerability is resolved since version RELEASE.2023-03-20T20-16-18Z.
