CWE-211 通过外部产生的错误消息导致的信息暴露
Information Exposure Through Externally-Generated Error Message
结构: Simple
Abstraction: Base
状态: Incomplete
被利用可能性: unkown
基本描述
The software performs an operation that triggers an external diagnostic or error message that is not directly generated by the software, such as an error generated by the programming language interpreter that the software uses. The error can contain sensitive system information.

可能的缓解方案
System Configuration
策略:
Configure the application's environment in a way that prevents errors from being generated. For example, in PHP, disable display_errors.
MIT-40 ['Implementation', 'Build and Compilation']
策略: Compilation or Build Hardening
Debugging information should not make its way into a production release.
MIT-40 ['Implementation', 'Build and Compilation']
策略: Environment Hardening
Debugging information should not make its way into a production release.
Implementation
策略:
Handle exceptions internally and do not display errors containing potentially sensitive information to a user. Create default error pages if necessary.
Implementation
策略:
The best way to prevent this weakness during implementation is to avoid any bugs that could trigger the external error message. This typically happens when the program encounters fatal errors, such as a divide-by-zero. You will not always be able to control the use of error pages, and you might not be using a language that handles exceptions.
