CWE-360 信任系统事件数据
Trust of System Event Data
结构: Simple
Abstraction: Base
状态: Incomplete
被利用可能性: High
基本描述
Security based on event locations are insecure and can be spoofed.
扩展描述
Events are a messaging system which may provide control data to programs listening for events. Events often do not have any type of authentication framework to allow them to be verified from a trusted source. Any application, in Windows, on a given desktop can send a message to any window on the same desktop. There is no authentication framework for these messages. Therefore, any message can be used to manipulate any process on the desktop if the process does not check the validity and safeness of those messages.

常见的影响
| 范围 | 影响 | 注释 |
|---|---|---|
| ['Integrity', 'Confidentiality', 'Availability', 'Access Control'] | ['Gain Privileges or Assume Identity', 'Execute Unauthorized Code or Commands'] | If one trusts the system-event information and executes commands based on it, one could potentially take actions based on a spoofed identity. |
可能的缓解方案
Architecture and Design
策略:
Never trust or rely any of the information in an Event for security.
示例代码
例
This example code prints out secret information when an authorized user activates a button:
bad Java
}
}
This code does not attempt to prevent unauthorized users from activating the button. Even if the button is rendered non-functional to unauthorized users in the application UI, an attacker can easily send a false button press event to the application window and expose the secret information.
