etcd Unauthenticated HTTP API Leak

The etcd HTTP API can be used without requiring authentication. As a result, keys containing sensitive information could be exposed. A user will also be able to update and delete keys without having to authenticate.

Impact

A remote attacker can deduce important data like usernames and passwords and modify or delete it.

Mitigation / Precaution

We recommend you implement an authentication mechanism for API to patch this issue.
