# DOM XSS en AngularJS con signos de menor que y comillas codificados
### XSS en DOM en una expresión de AngularJS con signos de menor y mayor y comillas dobles codificadas en HTML
Esta actividad muestra una vulnerabilidad XSS en DOM en una expresión de AngularJS utilizada por la función de búsqueda. AngularJS analiza nodos HTML que contienen la `ng-app` directiva y te permite evaluar expresiones dentro de dobles llaves `{{ }}` — lo cual puede ser aprovechado para ejecutar JavaScript incluso cuando los `<` y `>` signos de menor y mayor y las comillas están codificados en el lado HTML. Objetivo del laboratorio: inyectar una expresión de AngularJS que se ejecute `alert()`.
* El análisis del sitio con Wappalyzer indica la presencia de AngularJS.
* El recurso All The ThingsPayloads contiene payloads útiles para este caso (se proporcionan ejemplos a continuación).
Cargas útiles probadas
```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/es/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.
