CWE-584: Return Inside Finally Block
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The code has a return statement inside a finally block, which will cause any thrown exception in the try block to be discarded.
常见后果
影响范围: Other
技术影响: Alter Execution Logic
潜在缓解措施
阶段: Implementation
描述: Do not use a return statement inside the finally block. The finally block should have "cleanup" code.
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.)
