CWE VIEW: Hardware Design
 Objective Audience
RelationshipsThe following graph shows the tree-like relationships between
weaknesses that exist at different levels of abstraction. At the highest level, categories
and pillars exist to group weaknesses. Categories (which are not technically weaknesses) are
special CWE entries used to group weaknesses that share a common characteristic. Pillars are
weaknesses that are described in the most abstract fashion. Below these top-level entries
are weaknesses are varying levels of abstraction. Classes are still very abstract, typically
independent of any specific language or technology. Base level weaknesses are used to
present a more specific type of weakness. A variant is a weakness that is described at a
very low level of detail, typically limited to a specific language or technology. A chain is
a set of weaknesses that must be reachable consecutively in order to produce an exploitable
vulnerability. While a composite is a set of weaknesses that must all be present
simultaneously in order to produce an exploitable vulnerability.

Description
Extended Description
Common Consequences This table specifies different individual consequences
associated with the weakness. The Scope identifies the application security area that is
violated, while the Impact describes the negative technical impact that arises if an
adversary succeeds in exploiting this weakness. The Likelihood provides information about
how likely the specific consequence is expected to be seen relative to the other
consequences in the list. For example, there may be high likelihood that a weakness will be
exploited to achieve a certain impact, but a low likelihood that it will be exploited to
achieve a different impact.
