# HTTP/HTTPS - Heartbleed脆弱性

ssltest.pyとフィルタ済み出力レビューによるHeartbleed脆弱性の検証。

もし **Heartbleed** Webサイトで疑われる場合は、次のPythonスクリプトで検証してください:

{% embed url="<https://github.com/vulhub/vulhub/blob/master/openssl/CVE-2014-0160/ssltest.py>" %}

```bash
python3 ssltest.py 127.0.0.1 -p 8443
```

次のようなものが表示されたら:

<figure><img src="https://2001299964-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fl4EVJpcOrsgjSGsLI7p2%2Fuploads%2Fgit-blob-2d607c49eba4fe4ac1a45fb91ad1350b57bb5f5b%2FPasted%20image%2020230809205346.png?alt=media" alt="" width="563"><figcaption></figcaption></figure>

繰り返しのノイズを除外して、有用な出力だけを残します:

```bash
python3 ssltest.py 127.0.0.1 -p 8443 | grep "01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01" -v
```

この場合、有用なデータは表示されません。脆弱な対象では、この出力によって機密性の高いメモリ内容が明らかになることがあります。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hacking-notes.jord4n.pro/ja/ports-and-services/http-and-https-80-443/http-https-heartbleed-vulnerability.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
