CWE Version 4.14 Released : What’s New!

The Common Weakness Enumeration (CWE) project, a community-developed list of common software and hardware weakness types, has announced the release of version 4.14.

This latest version introduces significant updates and improvements, including new entries and a new view that enhances the understanding and categorization of security weaknesses.

New CWE Entries for Microprocessor Security

In the realm of microprocessor security, four brand-new CWEs have been added. These new entries address specific vulnerabilities that can be exploited in microprocessor hardware, reflecting the growing importance of hardware-level security in the cybersecurity landscape.

You can analyze a malware file, network, module, and registry activity with the ANY.RUN malware sandbox, and the Threat Intelligence Lookup that will let you interact with the OS directly from the browser.

The details of these new CWEs have not been disclosed in the provided search results, but their inclusion signifies a commitment to keeping the CWE list relevant to emerging security concerns.

• CWE-1420: Exposure of Sensitive Information during Transient Execution
• CWE-1421: Exposure of Sensitive Information in Shared Microarchitectural Structures during Transient Execution
• CWE-1422: Exposure of Sensitive Information caused by Incorrect Data Forwarding during Transient Execution
• CWE-1423: Exposure of Sensitive Information caused by Shared Microarchitectural Predictor State that Influences Transient Execution

New View for ISA/IEC 62443 Requirements

CWE version 4.14 introduces a new view titled “Weaknesses Addressed by ISA/IEC 62443 Requirements”.

This view is designed to align with the ISA/IEC 62443 series of standards, which are critical for securing industrial automation and control systems.

By mapping CWEs to these standards, the new view aids organizations in identifying and addressing weaknesses that could impact the security of industrial systems.

Improvements in Software Security

The release also brings improvements in the categorization and description of software security weaknesses.

The CWE-699 view, which focuses on software development, has been updated to provide a more structured and comprehensive framework for understanding weaknesses that arise during the software development lifecycle.

This view is particularly useful for architects, developers, educators, and assessment vendors, offering a clearer path for navigating and mitigating potential vulnerabilities in software.

The CWE project continues to evolve with the changing cybersecurity landscape, and version 4.14 is a testament to the ongoing efforts to provide a detailed and actionable classification of security weaknesses.

These updates will help security professionals, researchers, and developers better understand and protect against the vulnerabilities that threaten our software and hardware systems.

You can block malware, including Trojans, ransomware, spyware, rootkits, worms, and zero-day exploits, with Perimeter81 malware protection. All are extremely harmful, can wreak havoc, and damage your network.
