"The remote Redhat Enterprise Linux 7 host has a package installed that is affected by multiple vulnerabilities as
referenced in the RHSA-2016:0308 advisory.

    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 (not escaped). (CVE-2014-9649)

    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.
    (CVE-2014-9650)

    This update also fixes the following bug:

    * Previously, if the rabbit_mirror_queue_master did not return when using
    HA and 'auto_delete' queues, the RabbitMQ server blocked channels during
    termination. These channels would then have no associated connections and
    were displayed as 'unknown'. This issue has been resolved. (BZ#1303747)

    All rabbitmq-server users are advised to upgrade to these updated packages,
    which contain backported patches to correct these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
