CWE-451 (关键信息的UI错误表达) — Vulnerability Class 225

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. 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: Incorrect indicator: incorrect information is displayed, which prevents the user from understanding the true state of the product or the environment the product is monitoring, especially of potentially-dangerous conditions or operations. This can be broken down into several different subtypes. Overlay: an area of the display is intended to give critical information, but another process can modify the display by overlaying another element on top of it. The user is not interacting with the expected portion of the user interface. This is the problem that enables clickjacking attacks, although many other types of attacks exist that involve overlay. Icon manipulation: the wrong icon, or the wrong color indicator, can b…
