Which vulnerability is described as the most common and is mainly caused by human error?

• A. Misconfiguration
• B. Buffer Overflows
• C. CWE
• D. NVD

Answer: (A)

Misconfiguration vulnerabilities come from how systems are set up and managed, often driven by human error. When defaults aren’t adjusted, permissions are too permissive, unnecessary services are left running, or security controls aren’t properly applied, an attacker can gain easy access. Because configuration decisions happen at every layer of the stack and many administrators handle them, these mistakes are the most prevalent type of vulnerability in practice. They can affect networks, servers, databases, cloud resources, and applications, making them a broad and common threat. Buffer overflows, while serious, stem from coding mistakes that mishandle memory and require specific exploit conditions. They’re not described as the most common overall, and they’re not primarily caused by configuration errors. The CWE is a taxonomy of weakness types used to classify flaws, not a vulnerability itself. The NVD is a database of known vulnerabilities, a repository rather than a vulnerability type.
