# XSS DOM dans AngularJS avec chevrons et guillemets encodés
### XSS DOM dans une expression AngularJS avec des chevrons et des guillemets doubles encodés en HTML
Cette activité montre une vulnérabilité XSS DOM dans une expression AngularJS utilisée par la fonctionnalité de recherche. AngularJS analyse les nœuds HTML contenant le `ng-app` directive et vous permet d'évaluer des expressions entre doubles accolades `{{ }}` — ce qui peut être exploité pour exécuter du JavaScript même lorsque les `<` et `>` chevrons et les guillemets sont encodés côté HTML. Objectif du labo : injecter une expression AngularJS qui s'exécute `alert()`.
* L'analyse du site avec Wappalyzer indique la présence d'AngularJS.
* La ressource All The ThingsPayloads contient des payloads utiles pour ce cas (exemples fournis ci-dessous).
Payloads testés
```javascript
{{constructor.constructor('alert(1)')()}}
```
```
{{[].pop.constructor('alert/u00281/u0029')()}}
```

## 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/dom-xss-in-angularjs-with-encoded-angle-brackets-and-quotes.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.
