CWE-1122: Excessive Halstead Complexity

Weakness ID: 1122
Abstraction: Base
Structure: Simple
Status: Incomplete
Presentation Filter:
+ Description
The code is structured in a way that a Halstead complexity measure exceeds a desirable maximum.
+ Extended Description

A variety of Halstead complexity measures exist, such as program vocabulary size or volume.

This issue makes it more difficult to understand and/or maintain the software, which indirectly affects security by making it more difficult or time-consuming to find and/or fix vulnerabilities. It also might make it easier to introduce vulnerabilities.

+ Relationships

The table(s) below shows the weaknesses and high level categories that are related to this weakness. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as PeerOf and CanAlsoBe are defined to show similar weaknesses that the user may want to explore.

+ Common Consequences

The table below 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.
