2024 CWE Top 25 Most Dangerous Software Weaknesses

The Cybersecurity and Infrastructure Security Agency (CISA), in collaboration with the Homeland Security Systems Engineering and Development Institute (HSSEDI), operated by MITRE, has released the 2024 CWE Top 25 Most Dangerous Software Weaknesses. This annual list identifies the most critical software weaknesses that adversaries frequently exploit to compromise systems, steal sensitive data, or disrupt essential services.

Organizations are strongly encouraged to review this list and use it to inform their software security strategies. Prioritizing these weaknesses in development and procurement processes helps prevent vulnerabilities at the core of the software lifecycle.

Addressing these weaknesses is integral to CISA’s Secure by Design and Secure by Demand initiatives, which advocate for building and procuring secure technology solutions:

• Secure by Design: Encourages software manufacturers to implement security best practices throughout the design and development phases. By proactively addressing common weaknesses found in the CWE Top 25, manufacturers can deliver inherently secure products that reduce risk to end users. Learn more about Secure by Design here.
• Secure by Demand: Provides guidelines for organizations to drive security improvements when procuring software. Leveraging the CWE Top 25, customers can establish security expectations and ensure that their software vendors are committed to mitigating high-risk weaknesses from the outset. Explore how you can integrate Secure by Demand principles here.

Recommendations for Stakeholders:

• For Developers and Product Teams: Review the 2024 CWE Top 25 to identify high-priority weaknesses and adopt Secure by Design practices in your development processes.
• For Security Teams: Incorporate the CWE Top 25 into your vulnerability management and application security testing practices to assess and mitigate the most critical weaknesses.
• For Procurement and Risk Managers: Use the CWE Top 25 as a benchmark when evaluating vendors, and apply Secure by Demand guidelines to ensure that your organization is investing in secure products.

By following CISA’s initiatives, organizations can reduce vulnerabilities and strengthen application and infrastructure security. Incorporating the 2024 CWE Top 25 into cybersecurity and procurement strategies will enhance overall resilience.
