Red Hat Security Advisory 2015-0137-01 - Red Hat JBoss Fuse, based on Apache ServiceMix, provides a small-footprint, flexible, open source enterprise service bus and integration platform. Red Hat JBoss A-MQ, based on Apache ActiveMQ, is a standards compliant messaging system that is tailored for use in mission critical applications. This patch is an update to Red Hat JBoss Fuse 6.1.0 and Red Hat JBoss A-MQ 6.1.0. It includes a bug fix, which is documented in the readme.txt file included with the patch files. The following security issues are addressed in this release: It was found that if a configured LDAP server supported the unauthenticated authentication mechanism, the LDAPLoginModule implementation, provided by ActiveMQ Java Authentication and Authorization Service, would consider an authentication attempt to be successful for a valid user that provided an empty password. A remote attacker could use this flaw to bypass the authentication mechanism of an application using LDAPLoginModule, and assume a role of any valid user within that application.
