----------------------------------------
Summary: document: is mutual auth with DIGEST-MD5 insecure?
Key: ZOOKEEPER-3069
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3069
Project: ZooKeeper
Issue Type: Bug
Components: documentation
Reporter: Jan Zerebecki
The [documentation regarding mutual ZooKeeper server to server authentication
with
DIGEST-MD5|https://cwiki.apache.org/confluence/display/ZOOKEEPER/Server-Server+mutual+authentication#Server-Servermutualauthentication-DIGEST-MD5basedauthentication]
currently doesn't mention whether this is insecure. [DIGEST-MD5 was declared
obsolete in 2011 due to security problems.|https://tools.ietf.org/html/rfc6331]
This is in relation to whether this is an effective mitigation for
CVE-2018-8012 AKA ZOOKEEPER-1045, as mentioned in
[https://lists.apache.org/thread.html/c75147028c1c79bdebd4f8fa5db2b77da85de2b05ecc0d54d708b393@%3Cdev.zookeeper.apache.org%3E].
Would the following be a fitting addition to the documentation?:
DIGEST-MD5 based authentication should not be relied on for authentication as
it is insecure, it is only provided for test purposes.
