Descriptions

The optional ActiveMQ LDAP login module can be configured to use anonymous access to the LDAP server. In this case, for Apache ActiveMQ Artemis prior to version 2.16.0 and Apache ActiveMQ prior to versions 5.16.1 and 5.15.14, the anonymous context is used to verify a valid users password in error, resulting in no check on the password.

El módulo de inicio de sesión LDAP de ActiveMQ opcional puede ser configurado para usar el acceso anónimo al servidor LDAP. En este caso, para Apache ActiveMQ Artemis anterior a versión 2.16.0 y Apache ActiveMQ anterior a versiones 5.16.1 y 5.15.14, el contexto anónimo es usado para verificar una contraseña de usuario válida por error, resultando en una comprobación de la contraseña

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.

*Credits: Apache ActiveMQ would like to thank Gregor Tudan <gregor.tudan@cofinpro.de> for reporting this issue.
