CWE-407 算法复杂性

Inefficient Algorithmic Complexity

结构: Simple

Abstraction: Class

状态: Incomplete

被利用可能性: Low

基本描述

An algorithm in a product has an inefficient worst-case computational complexity that may be detrimental to system performance and can be triggered by an attacker, typically using crafted manipulations that ensure that the worst case is being reached.
