# SSRF ciega con detección fuera de banda
### SSRF ciega con detección fuera de banda
Este laboratorio usa un módulo de análisis que realiza una solicitud HTTP a la URL del **Referer** encabezado cuando se carga una página de producto. / Para resolver el laboratorio, debes usar este comportamiento para activar una solicitud al servidor público **Burp Collaborator**.
Comprobamos que la página recupera el valor de la cabecera Referer. / El objetivo es, por tanto, redirigir esta solicitud a nuestro cuerpo de Collaborator.
Basta con enviar una solicitud que contenga un Refererer malicioso, por ejemplo:
```
Referer: https://ld2xyh6ornbpdovp5ww0sartzk5bt1hq.oastify.com
```
El servidor realiza entonces una solicitud saliente, que aparece en Burp Collaborator, confirmando la operación de SSRF ciega.

## 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/ssrf/blind-ssrf-with-out-of-band-detection.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.
