# SSRF aveugle avec détection hors bande
### SSRF aveugle avec détection hors bande
Ce labo utilise un module d’analyse qui effectue une requête HTTP vers l’URL dans le **Referer** en-tête lorsqu’une page produit est chargée. / Pour résoudre le labo, vous devez utiliser ce comportement pour déclencher une requête vers le serveur public **Burp Collaborator**.
Nous constatons que la page récupère la valeur de l’en-tête Referer. / L’objectif est donc de rediriger cette requête vers notre serveur Collaborator.
Envoyez simplement une requête contenant un Referer malveillant, par exemple :
```
Referer: https://ld2xyh6ornbpdovp5ww0sartzk5bt1hq.oastify.com
```
Le serveur effectue alors une requête sortante, qui apparaît dans Burp Collaborator, confirmant le fonctionnement d’une SSRF aveugle.

## 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/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.
