CWE Version 3.0 Now Available

November 16, 2017 | Share this article

CWE Version 3.0 has been posted on the CWE List page. A detailed report is available that lists specific changes between Version 2.11 and Version 3.0.

The main changes for CWE 3.0 include:

Views:

  • One new view was added, Architectural Concepts, which is based on work by the Rochester Institute of Technology. We thank them for their contributions. This new view organizes weaknesses according to common architectural security tactics, and is intended to assist architects in identifying potential weaknesses when designing software.
  • There were numerous refinements to the Development Concepts view, primarily focusing on simplifying the top-level categories and improving the relationships amongst the individual weaknesses within (this is ongoing work that will continue into 2018).
  • The Seven Pernicious Kingdoms view was updated to more closely align it to the original white paper on which it based, and to make it easier to use.
  • Finally, three views were deprecated because they were duplicative or under-used within the community: Weaknesses Examined by SAMATE, Resource-specific Weaknesses, and Chain Elements.

Entries:

CWE 3.0 has three new Weaknesses:

Schema:

Summary:

There are now 714 weaknesses and a total of 1023 entries on the CWE List.

Changes for the new version includes the following:

  • New Entries Added:
17
  • Entries Deprecated:
24
  • Entries with Important Changes:
447
  • Entries with Major Changes:
756
  • Entries with Minor Changes:
118
  • Entries Unchanged:
238

See the complete list of changes at https://cwe.mitre.org/data/reports/diff_reports/v2.11_v3.0.html.

Future updates will be noted here and on the CWE Researcher email discussion list. Please send any comments or concerns to cwe@mitre.org.

IMPORTANT: Release of CWE 3.0 Includes Major Changes to CWE Schema

November 8, 2017 | Share this article

The release of CWE Version 3.0 includes major changes to the CWE Schema, which was updated from v5.4.4 to v6.0.

The main changes for the CWE Schema Version 6.0 include:

  • Made the <Weakness_Catalog> the only valid root element. Since the focus of CWE on weaknesses, make the <Weaknesses> child element required, while the other children (Views, Categories, and External_References) become optional.
  • Removed the <Compound_Element> and added a new "structure" attribute to <Weakness> element with values of: simple, chain, composite.
  • Added the <External_References> element to the weakness catalog that will function as a central collection of references that individual weaknesses can pull from as needed. As a side benefit, there is no longer a need to have a local reference ID as the main ID can be used.
  • Within the Applicable_Platform element, moved the CPE platform reference element to be an optional attribute on <Operating_System> because CPE is only applicable for the OS field and not languages, architectures, paradigms, or environments.
  • Changed the <Relationships> element to only be used for views and categories, and limited the values to memberOf and hasMember. As part of this, a new <Related_Weaknesses> element was added that holds all the different types of relationships that weaknesses can have with each other in order to eliminate the incorrect use memberOf and hasMember relationships with weaknesses, and the incorrect use of parentOf and childOf with views and categories.
  • Combined all the different note elements into a single <Notes> element. Also, to simplify the schema and have fewer elements in the resulting XML, added a type attribute that allows for a distinction between maintenance, platform, relationship, terminology, theoretical, and other.
  • Also, made minor modifications to the child elements of <View>, <Category>, and <Weakness>; renamed the <Description> top-level elements; and revised the StructuredTextType and added a new StructuredCodeType that leverages XHTML but includes a couple of existing attributes (language, nature).

See a detailed list of schema changes at https://cwe.mitre.org/data/reports/diff_reports/xsd_v5.4.4_v6.0.html.

Future updates will be noted here and on the CWE Researcher email discussion list. Please send any comments or concerns to cwe@mitre.org.

CWE a Major Focus of DARPA’s New System Security Integrated Through Hardware and Firmware (SSITH) Program

April 10, 2017 | Share this article

CWE is cited in an April 10, 2017 article on the DARPA website entitled “Baking Hack Resistance Directly into Hardware” as a major focus of DARPA’s new System Security Integrated Through Hardware and Firmware (SSITH) program.

As stated on the website, the purpose of the SSITH program is to "develop hardware design tools that provide security against hardware vulnerabilities that are exploited through software in Department of Defense (DoD) and commercial electronic systems. SSITH seeks to leverage current research in hardware design and software security to propel new research in the area of hardware security at the microarchitecture level."

CWE is mentioned in the article as follows: "SSITH specifically seeks to address the seven classes of hardware vulnerabilities listed in the Common Weakness Enumeration (cwe.mitre.org), a crowd-sourced compendium of security issues that is familiar to the information technology security community. In cyberjargon, these classes are: permissions and privileges, buffer errors, resource management, information leakage, numeric errors, crypto errors, and code injection. Researchers have documented some 2800 software breaches that have taken advantage of one or more of these hardware vulnerabilities, all seven of which are variously present to in the integrated microcircuitry of electronic systems around the world. Remove those hardware weaknesses … and you would effectively close down more than 40% of the software doors intruders now have available to them."

CWE Mentioned in Article about Software Code and Security on Information Age

March 31, 2017 | Share this article

CWE is mentioned as a main topic in a March 31, 2017 article entitled "Does software quality equal software security? It depends" on Information Age. The main topic of the article is a discussion of software code quality versus software code security.

CWE is the focus of a section of the article entitled "CWE," in which the author describes what CWE is and how to use it and other tools to check code for weaknesses. The author also states: "Checking against various CWEs can also be a step toward achieving industry compliance. And CWEs can also be associated with common vulnerabilities and exposures (CVE), another intersection between quality and security."

CWE is mentioned again as the author concludes the article: "Producing software free of CWEs or CVEs makes it quality code. However, failure to maintain the code with the latest updates of its individual component and/or using fuzz testing to truly harden the code against future threats is vital. Both are necessary to have secure software applications."
