CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product assigns the wrong ownership, or does not properly verify the ownership, of an object or resource.
常见后果
影响范围: Access Control
技术影响: Gain Privileges or Assume Identity
潜在缓解措施
阶段: Architecture and Design Operation
描述: Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
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-1999-1125
Program runs setuid root but relies on a configuration file owned by a non-root user.
