CWE-248: Uncaught Exception
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
An exception is thrown from a function, but it is not caught.
扩展描述
When an exception is not caught, it may cause the program to crash or expose sensitive information.
常见后果
影响范围: Availability Confidentiality
技术影响: DoS: Crash, Exit, or Restart Read Application Data
说明: An uncaught exception could cause the system to be placed in a state that could lead to a crash, exposure of sensitive information or other unintended behaviors.
检测方法
方法: Automated Static Analysis
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
有效性: High
