FAQ

CWEs are integrated into many source code analysis, security audit, and vulnerability management tools to automatically identify potential weaknesses in software. By understanding which CWEs are present in a system, teams can estimate the attack surface, anticipate future threats, and prioritize fixes before a flaw becomes an exploitable CVE.

They also allow for the establishment of risk profiles for projects or products, based on the nature and number of weaknesses identified. This facilitates decision-making for CISOs, CIOs, or compliance managers, particularly in DevSecOps approaches or during evaluations according to frameworks such as NIST or ISO 27002.

The CWE Top 25 is an annual list of the 25 most dangerous software security weaknesses. It is compiled by MITRE using public data from the NVD (National Vulnerability Database) and other sources, analyzing the frequency and impact of weaknesses associated with real-world CVEs.

This ranking is valuable for developers and security teams because it highlights the most common and critical errors, such as injections, buffer overflows, or authentication problems. By focusing on these priority weaknesses, organizations can quickly improve their security posture, even with limited resources.

The CWE list is maintained by the MITRE Corporation, the same organization that manages the CVE program. MITRE is supported by the U.S. Department of Homeland Security (DHS) and other public and private stakeholders to develop and update this knowledge base.

The community also plays a key role: researchers, publishers, governments, and industry professionals can propose new weaknesses, suggest modifications, or share feedback on the usefulness of existing entries. The database is public, freely accessible online, and continuously enriched to reflect the evolution of technologies and attack techniques.
