CWE-496: Public Data Assigned to Private Array-Typed Field
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
Assigning public data to a private array is equivalent to giving public access to the array.
常见后果
影响范围: Integrity
技术影响: Modify Application Data
说明: The contents of the array can be modified from outside the intended scope.
潜在缓解措施
阶段: Implementation
描述: Do not allow objects to modify private members of a class.
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.)
