# Uncontrolled Resource Consumption (CWE-400)

The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.

**Stack:** Kubernetes

- Prevalence: 高 频繁被利用
- Impact: 中 建议审查
- Prevention: 已记录 8 个修复示例

**OWASP:** Security Misconfiguration (A05:2021-Security Misconfiguration) - #5

## Description

Limited resources include memory, file system storage, database connection pool entries, and CPU. If an attacker can trigger the allocation of these limited resources, but the number or size of the resources is not controlled, then the attacker could cause a denial of service.

## Prevention

基于 1 条 Shoulder 检测规则的 Resource Exhaustion 预防策略。

### Kubernetes

Define CPU and memory resource limits to prevent resource exhaustion and denial of service

## Warning Signs

- [MEDIUM] Container is missing resource limits.
- [MEDIUM] containers missing resource limits

## Consequences

- 拒绝服务 (DoS):资源消耗
- 拒绝服务 (DoS):崩溃/退出/重启

## Mitigations

- 实施速率限制
- 使用资源配额
- 为操作设置超时

## Detection

- Total rules: 8
- Languages: go, javascript, typescript, yaml, python

## Rules by Language

### Yaml (1 rules)

- **Missing Resource Limits** [MEDIUM]: Detects containers missing resource limits.
  - Remediation: Define resource limits for containers.

```yaml
resources:
  limits:
    memory: "256Mi"
    cpu: "500m"
```
