The CWE is a community-developed list of software and hardware weaknesses maintained by the MITRE Corporation. Each CWE entry is labeled with a unique identifier and a detailed description of the weakness. CWEs are categorized based on various criteria, such as software design, implementation, and architectural weaknesses.
The CWE Top 25 List describes the most dangerous weaknesses. When used in conjunction with CVE entries, the pentester can develop a strong understanding of potential vulnerabilities.
