CWE-459: Incomplete Cleanup
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product does not properly "clean up" and remove temporary or supporting resources after they have been used.
常见后果
影响范围: Other Confidentiality Integrity
技术影响: Other Read Application Data Modify Application Data DoS: Resource Consumption (Other)
说明: It is possible to overflow the number of temporary files because directories typically have limits on the number of files allowed. This could create a denial of service problem.
潜在缓解措施
阶段: Architecture and Design Implementation
描述: Temporary files and other supporting resources should be deleted/released immediately after they are no longer needed.
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
