Red Hat Security Advisory 2016-0369-01 – RabbitMQ is an implementation of AMQP, the emerging standard for high performance enterprise messaging. The RabbitMQ server is a robust and scalable implementation of an AMQP broker. A cross-site scripting vulnerability was discovered in RabbitMQ, which allowed using api/ path info to inject and receive data. A remote attacker could use this flaw to create an “/api/…” URL, forcing a server error that resulted in the server returning an HTML page with embedded text from the URL. A response-splitting vulnerability was discovered in RabbitMQ. An /api/definitions URL could be specified, which then caused an arbitrary additional header to be returned. A remote attacker could use this flaw to inject arbitrary HTTP headers and possibly gain access to secure data.
