Descriptions

The (1) proton.reactor.Connector, (2) proton.reactor.Container, and (3) proton.utils.BlockingConnection classes in Apache Qpid Proton before 0.12.1 improperly use an unencrypted connection for an amqps URI scheme when SSL support is unavailable, which might allow man-in-the-middle attackers to obtain sensitive information or modify data via unspecified vectors.

Las clases (1) proton.reactor.Connector, (2) proton.reactor.Container y (3) proton.utils.BlockingConnection en Apache Qpid Proton en versiones anteriores a 0.12.1 usan de forma incorrecta una conexión cifrada para un esquema URI amqps cuando el soporte SSL no está disponible, lo que podría permitir a atacantes man-in-the-middle obtener información sensible o modificar datos a través de vectores no especificados.

Messaging applications using the Proton Python API to provision an SSL/TLS encrypted TCP connection may actually instantiate a non-encrypted connection without notice if SSL support is unavailable. This will result in all messages being sent in the clear without the knowledge of the user. Apache Qpid Proton python API versions starting at 0.9 and up to 0.12.0 are affected.
