Description Jonathan Christison 2021-01-27 14:54:13 UTC 
A flaw was found in Red Hat AMQ 6 and ActiveMQ Artemis (Red Hat AMQ 7) with the LDAP login module, if anonymous binds are enabled on the LDAP provider (zero length DN/password) and the LDAP module is configured to make use of these, client credentials are not correctly verified and authentication is effectively bypassed.
