CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product does not properly check inputs that are used for loop conditions, potentially leading to a denial of service or other consequences because of excessive looping.
常见后果
影响范围: Availability
技术影响: DoS: Resource Consumption (CPU)
潜在缓解措施
阶段: Implementation
描述: Do not use user-controlled data for loop conditions.
阶段: Implementation
描述: Perform input validation.
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.)
