CWE-228: Improper Handling of Syntactically Invalid Structure
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product does not handle or incorrectly handles input that is not syntactically well-formed with respect to the associated specification.
常见后果
影响范围: Integrity Availability
技术影响: Unexpected State DoS: Crash, Exit, or Restart DoS: Resource Consumption (CPU)
说明: If an input is syntactically invalid, then processing the input could place the system in an unexpected state that could lead to a crash, consume available system resources or other unintended behaviors.
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-2004-0270
