CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product does not properly prevent sensitive system-level information from being accessed by unauthorized actors who do not have the same level of access to the underlying system as the product does.
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 Implementation
描述: Production applications should never use methods that generate internal details such as stack traces and error messages unless that information is directly committed to a log that is not viewable by the end user. All error message text should be HTML entity encoded before being written to the log file to protect against potential cross-site scripting attacks against the viewer of the logs
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
观察示例
参考: CVE-2021-32638
Code analysis product passes access tokens as a command-line parameter or through an environment variable, making them visible to other processes via the ps command.
