CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product makes files or directories accessible to unauthorized actors, even though they should not be.
常见后果
影响范围: Confidentiality Integrity
技术影响: Read Files or Directories Modify Files or Directories
潜在缓解措施
阶段: Implementation System Configuration Operation
描述: When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to disable public access.
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
