CWE-538: Insertion of Sensitive Information into Externally-Accessible File or Directory
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product places sensitive information into files or directories that are accessible to actors who are allowed to have access to the files, but not to the sensitive information.
常见后果
影响范围: Confidentiality
技术影响: Read Files or Directories
潜在缓解措施
阶段: Architecture and Design Operation System Configuration
描述: Do not expose file and directory information to the user.
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

参考: CVE-2018-1999036
