Вкл. `http://localhost:3000` -> **Gitea** доступна.
Соединение с учетными данными для Axel.
Известная уязвимость XSS.
Мы создаем проект с описанием, содержащим:
```bash
Тест XSS
```
* Результат:
### Перехваченная почта через LinPEAS
содержимое письма:
* jobert\@localhost должен проверить репозиторий Gitea
Мы отправляем XSS-ссылку, содержащую скрипт эксфильтрации, который читает содержимое страницы `index.php` репозитория Gitea, кодирует его в Base64, затем отправляет на наш веб-сервер
{% code overflow="wrap" %}
```bash
ВЗЛОМАНО
```
{% endcode %}
#### Через наш веб-сервер
```bash
python -m http.server 8080
```
#### Перехваченное содержимое (декодировано из Base64):
```bash

## 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://hacking-notes.jord4n.pro/ru/web-vulnerabilities/owasp-top-10-vulnerabilities/vulnerability-cross-site-scripting-xss/xxs-source-code-theft.md?ask=&goal=
```
`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.
