CVE-2021-26117: ActiveMQ: LDAP-Authentication does not verify passwords on servers with anonymous bind

First published: Mon Sep 07 2020(Updated: )

A flaw was found in activemq. When 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. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
