The underlying weakness: Multiple Interpretations of UI Input

The UI has multiple interpretations of user input but does not prompt the user when it selects the less secure interpretation.

How developers prevent this class of flaw

  • Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
