???Top Threats and Vulnerabilities from 2024

In November 2024, Mitre released its annual CWE Top 25 Most Dangerous Software Weaknesses list, which ranks vulnerabilities based on a combination of frequency and severity. However, a report by VulnCheck has re-evaluated these rankings using a threat-centric approach, focusing on the number of known exploited vulnerabilities (KEVs) associated with each weakness.

Key Findings from VulnCheck's Analysis

• Vulnerability Context: VulnCheck emphasizes that while all vulnerabilities pose risks, the Mitre list prioritizes vulnerability counts without considering real-world exploitation. Their analysis indicates that vulnerabilities with evidence of exploitation should be addressed urgently[1].
• CWE Rankings Reevaluation: The report calculated total CVEs, KEVs, and the KEV-to-CVE ratio for each CWE over the same period as Mitre's research. This approach suggests that the rankings could change significantly when factoring in actual exploitation data[1].
• Outlier Observations: Certain CWEs, such as CWE-352 (Cross-Site Request Forgery) and CWE-476 (Null Pointer Dereference), raised questions about their inclusion in the top ranks due to low or no associated KEVs. Conversely, CWEs like CWE-79 (Cross-site Scripting) and CWE-89 (SQL Injection) were highlighted for their high KEV counts linked to widely used technologies[1].

Noteworthy CWEs Not in the Top 25

VulnCheck also identified several significant CWEs that did not make it to the top 25 list but are still concerning due to their exploitation potential. These include:

• CWE-284 (Improper Access Control): 541 CVEs, 11 KEVs.
• CWE-843 (Type Confusion): 96 CVEs, 6 KEVs.
• CWE-288 (Authentication Bypass): 33 CVEs, 5 KEVs[1].

Conclusion

VulnCheck's findings challenge the conventional rankings of software weaknesses by highlighting the importance of real-world exploitation data in assessing risk. Their analysis provides a more nuanced view of which vulnerabilities may truly be the most dangerous in practice.
