An issue was discovered in Pivotal RabbitMQ 3.x before 3.5.8 and 3.6.x before 3.6.6 and RabbitMQ for PCF 1.5.x before 1.5.20, 1.6.x before 1.6.12, and 1.7.x before 1.7.7. MQTT (MQ Telemetry Transport) connection authentication with a username/password pair succeeds if an existing username is provided but the password is omitted from the connection request. Connections that use TLS with a client-provided certificate are not affected.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - rabbitmq: MQTT connection authentication succeeds with empty password (CVE-2016-9877)

  - An issue was discovered in these Pivotal RabbitMQ versions: all 3.4.x versions, all 3.5.x versions, and     3.6.x versions prior to 3.6.9; and these RabbitMQ for PCF versions: all 1.5.x versions, 1.6.x versions     prior to 1.6.18, and 1.7.x versions prior to 1.7.15. Several forms in the RabbitMQ management UI are     vulnerable to XSS attacks. (CVE-2017-4965, CVE-2017-4967)

  - An issue was discovered in these Pivotal RabbitMQ versions: all 3.4.x versions, all 3.5.x versions, and     3.6.x versions prior to 3.6.9; and these RabbitMQ for PCF versions: all 1.5.x versions, 1.6.x versions     prior to 1.6.18, and 1.7.x versions prior to 1.7.15. RabbitMQ management UI stores signed-in user     credentials in a browser's local storage without expiration, making it possible to retrieve them using a     chained attack. (CVE-2017-4966)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - rabbitmq: MQTT connection authentication succeeds with empty password (CVE-2016-9877)

Note that Nessus has not tested for this issue but has instead relied on the package manager's report that the package is installed.

Pivotal.io reports :

All versions prior to 3.8.16 are prone to a denial of service vulnerability due to improper input validation in AMQP 1.0 client connection endpoint.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-3374-1 advisory.

    It was discovered that RabbitMQ incorrectly handled MQTT (MQ Telemetry Transport) authentication. A remote     attacker could use this issue to authenticate successfully with an existing username by omitting the     password.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

- Fix 0.0.0 as a version.

  - Ver. 3.6.6

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update for rabbitmq-server fixes the following issue :

  - CVE-2016-9877: An issue in Pivotal RabbitMQ caused     connection authentication with a username/password pair     to succeed if an existing username was provided but the     password is omitted from the connection request.
    Connections that use TLS with a client-provided     certificate were not affected (bsc#1017642).

Pivotal.io reports :

MQTT (MQ Telemetry Transport) connection authentication with a username/password pair succeeds if an existing username is provided but the password is omitted from the connection request. Connections that use TLS with a client-provided certificate are not affected.

It was discovered that RabbitMQ, an implementation of the AMQP protocol, didn't correctly validate MQTT (MQ Telemetry Transport) connection authentication. This allowed anyone to login to an existing user account without having to provide a password.
