## NISTリンク

<https://nvd.nist.gov/vuln/detail/CVE-2023-44487>

## 説明

HTTP/2プロトコルには、リクエストのキャンセルが複数のストリームを迅速にリセットできるため、サーバーのリソースを大量に消費させる可能性があり、これがサービス拒否 (DoS) 攻撃を引き起こす原因となります。この脆弱性は、2023年8月から10月にかけて実際に悪用されました。

## Keeperへの影響

Keeper Securityのアプリケーションサーバーは、AWS Shieldによって保護されており、DDoS攻撃から守られています。そのため、Keeperはこの攻撃には影響を受けません。詳細については、[Amazonのブログ](https://aws.amazon.com/jp/blogs/security/how-aws-protects-customers-from-ddos-events/)に掲載されています。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.keeper.io/release-notes/jp/keeper-security/security-advisories/cve-2023-44487.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
