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.

"Updated Grid component packages that fix one security issue, multiple
bugs, and add various enhancements are now available for Red Hat
Enterprise MRG 2.0 for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link 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 Grid provides high-throughput computing and enables enterprises to
achieve higher peak computing capacity as well as improved
infrastructure utilization by leveraging their existing technology to
build high performance grids. MRG Grid provides a job-queueing
mechanism, scheduling policy, and a priority scheme, as well as
resource monitoring and resource management. Users submit their jobs
to MRG Grid, where they are placed into a queue. MRG Grid then chooses
when and where to run the jobs based upon a policy, carefully monitors
their progress, and ultimately informs the user upon completion.

A flaw was discovered in Cumin where it would log broker
authentication credentials to the Cumin log file. A local user
exploiting this flaw could connect to the broker outside of Cumin's
control and perform certain operations such as scheduling jobs,
setting attributes on jobs, as well as holding, releasing or removing
jobs. The user could also use this to, depending on the defined ACLs
of the broker, manipulate message queues and other privileged
operations. (CVE-2011-2925)

In addition, these updated packages for Red Hat Enterprise Linux 6
provide numerous bug fixes and enhancements for the Grid component of
MRG. Some of the most important enhancements include :

* Expanded support of EC2 features, including EBS and VPC.

* Improved negotiation performance.

* Reduced shadow memory usage.

* Integrated configuration and management experience, including
real-time monitoring, diagnostics, and configuration templates.

Release Notes :

* When MRG Grid ran on a node with multiple network interfaces, it
tried to estimate the correct interface for its communications with
the remaining MRG Grid nodes. As a consequence, the node could have
failed to communicate with other parts of MRG Grid correctly if the
wrong interface had been chosen. As a workaround to this issue, MRG
Grid can be forced to use a specific network interface by setting the
NETWORK_INTERFACE parameter to the IP address of that interface. To
determine which interface was used by MRG Grid when it fails to
communicate with other parts of the grid, include the D_HOSTNAME
variable in the logging configuration of the corresponding daemon.
(BZ#728285)

* The remote configuration database requires an update to include
changes for MRG Grid version 2.0.1. But the database snapshot provided
with MRG only contains a basic configuration, and thus loading the
database snapshot would replace the existing pool configuration. To
solve this issue, the upgrade-wallaby-db tool which upgrades an
existing deployment's database has to be used. This tool can be
downloaded from the following page:
https://access.redhat.com/kb/docs/DOC-58404

* With this update, the Elastic Compute Cloud Grid ASCII Helper
Protocol (EC2 GAHP) is preferred over AMAZON GAHP. The
condor-ec2-enhanced-hooks package has been updated to detect the
correct GAHP for the EC2 Enhanced feature based upon what GAHPs are
available on the scheduler. To ensure that jobs are routed to the
proper resources, the 'set_gridresource = 'amazon'; \' setting should
be removed from all existing EC2 Enhanced routes in a MRG Grid's
configuration. (BZ#688717)
