Weakness ProhibitedUse of Redundant Code
Abstraction: Class · Status: Incomplete
The product has multiple functions, methods, procedures, macros, etc. that contain the same code, i.e., the code has been copied or duplicated.
Dimensions
- Behavior-Type: Use
- Code-Property: Redundant
- Code-Type: Code
Mapping guidance
This entry is primarily a quality issue with no direct security implications.
Look for weaknesses that are focused specifically on insecure behaviors that have more direct security implications.
Modes of introduction
Detection methods
Automated Static Analysis
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
