CWE-451 关键信息的UI错误表达

User Interface (UI) Misrepresentation of Critical Information

结构: Simple

Abstraction: Class

状态: Draft

被利用可能性: unkown

基本描述

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.

扩展描述

If an attacker can cause the UI to display erroneous data, or to otherwise convince the user to display information that appears to come from a trusted source, then the attacker could trick the user into performing the wrong action. This is often a component in phishing attacks, but other kinds of problems exist. For example, if the UI is used to monitor the security state of a system or network, then omitting or obscuring an important indicator could prevent the user from detecting and reacting to a security-critical event.

UI misrepresentation can take many forms:

可能的缓解方案

Implementation

策略: Input Validation

Perform data validation (e.g. syntax, length, etc.) before interpreting the data.

Architecture and Design

策略: Output Encoding

Create a strategy for presenting information, and plan for how to display unusual characters.

Notes

Maintenance
This entry could be broken down into smaller entries. It is probably more like a Class than a Base.
Research Gap
Misrepresentation problems are frequently studied in web browsers, but there are no known efforts for classifying these kinds of problems in terms of the shortcomings of the interface. In addition, many misrepresentation issues are resultant.
