CWE Version 1.11 Now Available

CWE Version 1.11 has been posted on the CWE List page. A detailed report is available that lists specific changes between Version 1.10 and Version 1.11.

The main changes include: (1) creation of 7 new entries, mostly for race conditions and "functionality inclusion" issues; (2) deprecation of one entry; (3) changes in the names of 26 entries, and descriptions of 40 entries; (4) modified mitigations for 20 entries, primarily to further normalize the mitigations in the Top 25; (5) updates to relationships for 35 entries, primarily for sub-tree reorganization for race conditions; (6) updates to the demonstrative examples in 23 entries; and (7) major changes to 135 entries.

PDF documents have been updated to display graphs of views such as the Research View (CWE-1000) and the Development View (CWE-699), and a "Printable CWE" document lists all of the entries in CWE.

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

Common Weakness Scoring System (CWSS) Introductory White Paper Now Available

A white paper entitled Introduction to the Common Weakness Scoring System (CWSS) is now available for community review and download on the CWE Web site. CWSS is co-sponsored by the National Cyber Security Division of the U.S. Department of Homeland Security, and led by MITRE's CWE Team.

The white paper introduces the CWSS effort and explains how it can be used for assessing and prioritizing possible software architecture, design, code, and implementation weaknesses that "might be introduced into an application, which in some cases can contribute to a vulnerability within that software ... For example, a buffer overflow vulnerability might arise from a weakness in which the programmer does not properly validate the length of an input buffer. This weakness only contributes to a vulnerability if the input buffer can be influenced by a malicious party, and the malicious buffer is copied to a smaller buffer." In addition to helping developers score the severity of weaknesses, CWSS also provides a way for software consumers to "know what they should worry about the most, and what to ask for to get a more secure product from their vendors and suppliers."

Topics discussed in the white paper include CWSS's six primary stakeholders; design considerations for the framework and metrics; various scoring methods that might need to be supported; introduction of CWSS's "Vignette" concept, which is a "shareable, formalized way to define a particular environment, the role that software plays within that environment, and its priorities with respect to software security"; a CWSS Version 0.1 scoring list; considerations for CWSS beyond Version 0.1; additional scoring factors; activities for future versions; and ways the community can participate.

The majority of the development and refinement of the first major version of CWSS is expected to occur in 2011. We encourage members of the community to review the white paper and send feedback to cwss@mitre.org.

New ISO/IEC Report Lists the 51 Most Common Vulnerabilities in Programming Languages

The International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) issued a joint technical report (TR) on September 29, 2010 entitled "ISO/IEC TR 24772:2010, Information technology -- Programming languages -- Guidance to avoiding vulnerabilities in programming languages through language selection and use" that describes classes of programming language vulnerabilities—features of languages that encourage or permit the writing of code that contains application vulnerabilities. The report describes 51 vulnerabilities in languages themselves, as well as 20 additional vulnerabilities that could be avoided by offering a richer set of library routines.

According to the report, programming language vulnerabilities should especially be avoided "in the development of systems where assured behaviour is required for security, safety, mission critical and business critical software. In general, this guidance is applicable to the software developed, reviewed, or maintained for any application." The report explains that the vulnerabilities occur in programming languages due to issues arising from incomplete or evolving language specifications, human cognitive limitations, lack of predictable execution, lack of portability and interoperability, inadequate language intrinsic support, and language features prone to erroneous use.

All of the vulnerabilities are documented in a standardized, language-independent format that allows readers to quickly comprehend and utilize the information. The report also provides standardized templates for the community to use when a new programming language vulnerability and/or resulting application vulnerability is identified.

No one language contains all of the vulnerabilities described in the report, but most are very common. Of the programming language and application vulnerabilities detailed in the report, 17 are also on the 2010 CWE/SANS Top 25 Most Dangerous Software Errors list. Future editions of the report will cover the remainder of the Top 25, any additional programming language and application vulnerabilities found in follow-on work, and annexes that apply the general guidance to particular programming languages.

The report is available for purchase from http://www.iso.org and http://www.ansi.org.

2010 CWE/SANS Top 25 Programming Errors List Receives Extensive News Coverage

CWE and the SANS Institute posted the completed 2010 CWE/SANS Top 25 Programming Errors on the CWE and SANS Web sites on February 16, 2010. A collaboration between the SANS Institute, MITRE, and over 40 top software security experts in the U.S. and Europe, the list provides detailed descriptions of the top 25 programming errors along with authoritative guidance for mitigating and avoiding them.

The release received extensive news media coverage:

CWE and Top 25 Are Main Topics of Federal News Radio Interview

Federal News Radio interviewed CWE/CAPEC Program Manager Robert A. Martin on March 10, 2010 about CWE and the Top 25 Most Dangerous Programming Errors. In the interview, entitled "Top federal software security holes exposed," Martin states: "The big problem is that traditional education in our country and across the world for software developers, for testers, for program managers has pretty much ignored this area. We put them into our software because we didn't know how they happened. So the CWE, the full Common Weakness Enumeration and then this prioritized part of the CWE, which we're calling the Top 25 Most Dangerous Programming Errors is basically an education tool at the first level. These are issues you should be aware of. You should ask your developers "have you been trained to recognize these if someone puts them in accidentally? Do you know how to program around these so that you don't introduce them?" You test people. "Do you know how to try to misuse and abuse your system?" So that, if there any of these latently in your software, you can find them before the user has it in his hands." A summary of the interview was published on the Federal News Radio Web site.

CWE Mentioned in Federal News Radio Interview about Software Assurance

Federal News Radio interviewed Joe Jarzombek, director for software assurance in the National Cyber Security Division of the Department of Homeland Security, on March 3, 2010 about software assurance. In the interview, entitled, "Software assurance affects more than just programmers," Jarzombek "explains why the CWE benefits cyber security -- and why this impacts more than programmers." A summary of the interview was published on the Federal News Radio Web site.

2010 Top 25 Most Dangerous Programming Errors List Now Available

The 2010 version of the SANS/MITRE Top 25 Most Dangerous Programming Errors that can lead to serious software vulnerabilities is now available on the CWE and SANS Web sites. Based primarily on the CWE List and leveraging the SANS Top 20 attack vectors, the main goal of the Top 25 list is to stop vulnerabilities at the source by educating programmers on how to eliminate all-too-common mistakes before software is even shipped. The list is a tool for education and awareness that will help programmers to prevent the kinds of vulnerabilities that plague the software industry. Software consumers may also use the list to help them to ask for more secure software, and software managers and CIOs can use the Top 25 as a measuring stick of progress in their efforts to secure their software.

Updates for the 2010 version include substantial improvements to the 2009 list. The structure of the list has been modified to distinguish mitigations and general secure programming principles from more concrete weaknesses. This year's Top 25 entries are prioritized using inputs from over 20 different organizations, who evaluated each weakness based on prevalence and importance. The 2010 version introduces focus profiles that allow developers and other users to select the parts of the Top 25 that are most relevant to their concerns. The 2010 version also adds a small set of the most effective "Monster Mitigations," which help developers to reduce or eliminate entire groups of the Top 25 weaknesses, as well as many of the other 800 weaknesses that are documented in the Common Weakness Enumeration (CWE). Finally, many high-level weaknesses from the 2009 version have been replaced with lower-level variants that are more actionable.

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

Security Automation Is Main Focus of DoD's IAnewsletter

"Security Automation: A New Approach to Managing and Protecting Critical Information" is the main topic of the Winter 2010 issue of the Department of Defense's (DoD) Information Assurance Technology Analysis Center's (IATAC) IAnewsletter.

According to the newsletter, a security automation strategy will enable automation of "many security and configuration management, compliance, and network defense functions and give our [DoD] system administrators and network defenders a chance to succeed." Specific articles topics include: An Introduction to Security Automation; Security Automation: A New Approach Managing and Protecting Critical Information; Security Content Automation Protocol; Secure Configuration Management (SCM); DoD Activities Underway to Mature SCAP Standards; Why Industry Needs Federal Government Leadership to Gain the Benefits of Security Automation; and Practicing Standards-Based Security Assessment and Management.

In addition, MITRE's CVE, CCE, CPE, and OVAL information assurance data standards are mentioned throughout the issue, especially with regard to how they are utilized by the National Institute of Standards and Technology's (NIST) Security Content Automation Protocol (SCAP) to help enable automated, standards-based security assessment and management.

The newsletter is free to download from the IATAC Web site.
