CWE-397: Declaration of Throws for Generic Exception
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product throws or raises an overly broad exceptions that can hide important details and produce inappropriate responses to certain conditions.
扩展描述
Declaring a method to throw Exception or Throwable promotes generic error handling procedures that make it difficult for callers to perform proper error handling and error recovery. For example, Java's exception mechanism makes it easy for callers to anticipate what can go wrong and write code to handle each specific exceptional circumstance. Declaring that a method throws a generic form of exception defeats this system.
常见后果
影响范围: Non-Repudiation Other
技术影响: Hide Activities Alter Execution Logic
说明: Throwing a generic exception can hide details about unexpected adversary activities by making it difficult to properly troubleshoot error conditions during execution.
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.)
