# SSRF Cega com Detecção Out-of-Band
### SSRF cego com detecção fora de banda
Este laboratório usa um módulo de análise que faz uma requisição HTTP para a URL no **Referer** cabeçalho quando uma página de produto é carregada. / Para resolver o laboratório, você deve usar esse comportamento para disparar uma requisição ao servidor público **Burp Collaborator**.
Percebemos que a página recupera o valor do cabeçalho Referer. / Portanto, o objetivo é redirecionar essa requisição para o nosso Collaborator.
Basta enviar uma consulta contendo um Referer malicioso, por exemplo:
```
Referer: https://ld2xyh6ornbpdovp5ww0sartzk5bt1hq.oastify.com
```
O servidor então realiza uma consulta de saída, que aparece no Burp Collaborator, confirmando a operação de SSRF cego.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## 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/pt-br/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.
