CWE-405 不对称的资源消耗（放大攻击）

Asymmetric Resource Consumption (Amplification)

结构: Simple

Abstraction: Class

状态: Incomplete

被利用可能性: unkown

基本描述

Software that does not appropriately monitor or control resource consumption can lead to adverse system performance.

扩展描述

This situation is amplified if the software allows malicious users or attackers to consume more resources than their access level permits. Exploiting such a weakness can lead to asymmetric resource consumption, aiding in amplification attacks against the system or the network.
