AI-analyzed exploit summary This Go-based exploit demonstrates CVE-2021-43858, a privilege escalation vulnerability in MinIO. It creates a new admin user by exploiting improper access control in the MinIO admin API.
Description
MinIO is a Kubernetes native application for cloud storage. Prior to version `RELEASE.2021-12-27T07-23-18Z`, a malicious client can hand-craft an HTTP API call that allows for updating policy for a user and gaining higher privileges. The patch in version `RELEASE.2021-12-27T07-23-18Z` changes the accepted request body type and removes the ability to apply policy changes through this API. There is a workaround for this vulnerability: Changing passwords can be disabled by adding an explicit `Deny` rule to disable the API for users.
