Summary

The default configuration for Apache Qpid 0.20 and earlier, when the federation_tag attribute is enabled, accepts AMQP connections without checking the source user ID, which allows remote attackers to bypass authentication and have other unspecified impact via an AMQP request.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Authentication Abuse
    An attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation. In such an attack an authentication mechanism is functioning but a carefully controlled sequence of events causes the mechanism to grant access to the attacker. This attack may exploit assumptions made by the target's authentication procedures, such as assumptions regarding trust relationships or assumptions regarding the generation of secret values. This attack differs from Authentication Bypass attacks in that Authentication Abuse allows the attacker to be certified as a valid user through illegitimate means, while Authentication Bypass allows the user to access protected material without ever being certified as an authenticated user. This attack does not rely on prior sessions established by successfully authenticating users, as relied upon for the "Exploitation of Session Variables, Resource IDs and other Trusted Credentials" attack patterns.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Utilizing REST's Trust in the System Resource to Register Man in the Middle
    This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to place man in the middle once SSL is terminated. Rest applications premise is that they leverage existing infrastructure to deliver web services functionality. An example of this is a Rest application that uses HTTP Get methods and receives a HTTP response with an XML document. These Rest style web services are deployed on existing infrastructure such as Apache and IIS web servers with no SOAP stack required. Unfortunately from a security standpoint, there frequently is no interoperable identity security mechanism deployed, so Rest developers often fall back to SSL to deliver security. In large data centers, SSL is typically terminated at the edge of the network - at the firewall, load balancer, or router. Once the SSL is terminated the HTTP request is in the clear (unless developers have hashed or encrypted the values, but this is rare). The attacker can utilize a sniffer such as Wireshark to snapshot the credentials, such as username and password that are passed in the clear once SSL is terminated. Once the attacker gathers these credentials, they can submit requests to the web service provider just as authorized user do. There is not typically an authentication on the client side, beyond what is passed in the request itself so once this is compromised, then this is generally sufficient to compromise the service's authentication scheme.
  • Man in the Middle Attack
    This type of attack targets the communication between two components (typically client and server). The attacker places himself in the communication channel between the two components. Whenever one component attempts to communicate with the other (data flow, authentication challenges, etc.), the data first goes to the attacker, who has the opportunity to observe or alter it, and it is then passed on to the other component as if it was never intercepted. This interposition is transparent leaving the two compromised components unaware of the potential corruption or leakage of their communications. The potential for Man-in-the-Middle attacks yields an implicit lack of trust in communication or identify between two components.

broker-to-broker connection, rather than a client-to-server

"Updated Messaging component packages that fix multiple security
issues, several bugs, and add various enhancements are now available
for Red Hat Enterprise MRG 2.3 for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

Red Hat Enterprise MRG (Messaging, Realtime, and Grid) is a
next-generation IT infrastructure for enterprise computing. MRG offers
increased performance, reliability, interoperability, and faster
computing for enterprise customers.

MRG Messaging is a high-speed reliable messaging distribution for
Linux based on AMQP (Advanced Message Queuing Protocol), an open
protocol standard for enterprise messaging that is designed to make
mission critical messaging widely available as a standard service, and
to make enterprise messaging interoperable across platforms,
programming languages, and vendors. MRG Messaging includes an AMQP
0-10 messaging broker; AMQP 0-10 client libraries for C++, Java JMS,
and Python; as well as persistence libraries and management tools.

It was found that the Apache Qpid daemon (qpidd) treated AMQP
connections with the federation_tag attribute set as a
broker-to-broker connection, rather than a client-to-server
connection. This resulted in the source user ID of messages not being
checked. A client that can establish an AMQP connection with the
broker could use this flaw to bypass intended authentication. For
Condor users, if condor-aviary is installed, this flaw could be used
to submit jobs that would run as any user (except root, as Condor does
not run jobs as root). (CVE-2012-4446)

It was found that the AMQP type decoder in qpidd allowed arbitrary
data types in certain messages. A remote attacker could use this flaw
to send a message containing an excessively large amount of data,
causing qpidd to allocate a large amount of memory. qpidd would then
be killed by the Out of Memory killer (denial of service).
(CVE-2012-4458)

An integer overflow flaw, leading to an out-of-bounds read, was found
in the Qpid qpid::framing::Buffer::checkAvailable() function. An
unauthenticated, remote attacker could send a specially crafted
message to Qpid, causing it to crash. (CVE-2012-4459)

The CVE-2012-4446, CVE-2012-4458, and CVE-2012-4459 issues were
discovered by Florian Weimer of the Red Hat Product Security Team.

This update also fixes several bugs and adds enhancements.
Documentation for these changes will be available shortly from the
Technical Notes document linked to in the References section.

All users of the Messaging capabilities of Red Hat Enterprise MRG are
advised to upgrade to these updated packages, which resolve these
issues, and fix the bugs and add the enhancements noted in the Red Hat
Enterprise MRG 2 Technical Notes. After installing the updated
packages, stop the cluster by either running 'service qpidd stop' on
all nodes, or 'qpid-cluster --all-stop' on any one of the cluster
nodes. Once stopped, restart the cluster with 'service qpidd start' on
all nodes for the update to take effect."
