CWE-488: Exposure of Data Element to Wrong Session
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product does not sufficiently enforce boundaries between the states of different sessions, causing data to be provided to, or used by, the wrong session.
常见后果
影响范围: Confidentiality
技术影响: Read Application Data
潜在缓解措施
阶段: Architecture and Design
描述: Protect the application's sessions from information leakage. Make sure that a session's data is not used or visible by other sessions.
阶段: Testing
描述: Use a static analysis tool to scan the code for information leakage vulnerabilities (e.g. Singleton Member Field).
阶段: Architecture and Design
描述: In a multithreading environment, storing user data in Servlet member fields introduces a data access race condition. Do not use member fields to store information in the Servlet.
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
