CWE-447: Unimplemented or Unsupported Feature in UI
A UI function for a security feature appears to be supported and gives feedback to the user that suggests that it is supported, but the underlying functionality is not implemented.
How it's found
Unimplemented or Unsupported Feature in UI 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.
Consequences
- Varies by Context, Unexpected State
Mitigations
- Testing: Perform functionality testing before deploying the application.
Where this fits in a TurboPentest engagement
This weakness is not covered by the automated black-box pentest. IntegSec pentesters cover it in a manual engagement.
