CWE-313: Cleartext Storage in a File or on Disk
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product stores sensitive information in cleartext in a file, or on disk.
扩展描述
The sensitive information could be read by attackers with access to the file, or with physical or administrator access to the raw disk. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information.
常见后果
影响范围: Confidentiality
技术影响: Read Application Data
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.)
