The underlying weakness: User Interface (UI) Misrepresentation of Critical Information
The user interface (UI) does not properly represent critical information to the user, allowing the information - or its source - to be obscured or spoofed. This is often a component in phishing attacks.
How developers prevent this class of flaw
- Perform data validation (e.g. syntax, length, etc.) before interpreting the data.
- Create a strategy for presenting information, and plan for how to display unusual characters.
