Cross-site Request Forgery (CSRF)

Affecting github.com/coreos/etcd/etcdserver package, versions <3.4

Overview

github.com/coreos/etcd/etcdserver is a distributed reliable key-value store for the most critical data of a distributed system.

Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF). An attacker can set up a website that tries to send a POST request to the etcd server and modify a key. Adding a key is done with PUT so it is theoretically safe (can't PUT from an HTML form or such) but POST allows creating in-order keys that an attacker can send.

Remediation

Upgrade github.com/coreos/etcd/etcdserver to version 3.4 or higher.
