How to fix?

A fix was pushed into the master branch but not yet published.

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 Path Traversal which allows users authorized for admin:ServerUpdate to selectively trigger an error that in response, returns the content of the path requested.

Note: The issue was resolved since version RELEASE.2022-07-29T19-40-48Z

PoC:

mc admin update alias/ /etc/passwd

The error response will contain the contents of the /etc/passwd file.

Mitigation:

Disabling the ServerUpdate API by denying the admin:ServerUpdate action for your admin users via IAM policies.
