CWE-561: Dead Code
The product contains dead code, which can never be executed.
How it's found
Dead Code is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
Dead code is code that can never be executed in a running program. The surrounding code makes it impossible for a section of code to ever be executed.
Consequences
- Quality Degradation: Dead code that results from code that can never be executed is an indication of problems with the source code that needs to be fixed and is an indication of poor quality.
- Reduce Maintainability
Mitigations
- Implementation: Remove dead code before deploying the application.
