Extended Description

This issue makes it more difficult to understand and/or maintain the product, 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. This issue can make the product perform more slowly. If the relevant code is reachable by an attacker, then this performance problem might introduce a vulnerability.

Frequently Asked Questions

What is CWE-1120: Excessive Code Complexity?+

CWE-1120: Excessive Code Complexity is a Common Weakness Enumeration (CWE) entry maintained by MITRE. The code is too complex, as calculated using a well-defined, quantitative measure. This issue makes it more difficult to understand and/or maintain the product, 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. This issue can make the product perform more slowly. If the relevant code is reachable by an attacker, then this performance problem might introduce a vulnerability.

What are the security consequences of Excessive Code Complexity?+

If exploited, CWE-1120 (Excessive Code Complexity) it can compromise Other, leading to outcomes such as Reduce Maintainability and Reduce Performance.

What is the difference between a CWE and a CVE?+

A CWE (Common Weakness Enumeration) like CWE-1120 describes a category of software weakness — the underlying flaw type. A CVE (Common Vulnerabilities and Exposures) identifies a specific, real-world vulnerability in a particular product. In short, a CWE is the kind of mistake, and a CVE is an instance of that mistake being found in software.
