Exposure of Resource to Wrong Sphere


Severity High
Score 8.8/10


The package is a Multi-Cloud Object Storage framework. All users on Windows in versions prior to 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.
