Quality Weaknesses with Indirect Security Impacts
A view in the Common Weakness Enumeration published by The MITRE Corporation.
Views in the Common Weakness Enumeration (CWE) represent one perspective with which to consider a set of weaknesses.
CWE identifiers in this view (slice) are quality issues that only indirectly make it easier to introduce a vulnerability and/or make the vulnerability more difficult to detect or mitigate.
Assessment Tool Vendors
This view makes it easier for assessment vendors to identify and improve coverage for quality-related weaknesses.
This view makes it easier for software vendors to identify important issues that may make their software more difficult to maintain, perform efficiently or reliably, or secure.
This view makes it easier for developers to identify and learn about issues that might make their code more difficult to maintain, perform efficiently or reliably, or secure.
