CWE-1093: Excessively Complex Data Representation
Official CWE-1093 CWE context with Glexia analysis, remediation guidance, related CVEs, and ATT&CK context.
Glexia's Take
CWE-1093: Excessively Complex Data Representation
Excessively Complex Data Representation represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Other: Reduce Maintainability,Increase Analytical Complexity: This issue makes it more difficult to understand 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.
- Other: Reduce Performance
Developer Pattern
CWE-1093 is the kind of defect developers can usually prevent with explicit validation, safer framework defaults, and tests that exercise hostile input or unsafe state transitions.
Confidence
high confidence from CWE-1093, 4.20.
Official CWE Definition
CWE-1093: Excessively Complex Data Representation
The product uses an unnecessarily complex internal representation for its data structures or interrelationships between those structures.
