Vulnerability Name: Host Header Injection Redirect

How it was found

Vulnerability Description: Open redirection is sometimes used as a part of phishing attacks that confuse visitors about which web site they are visiting.

Remediation: If possible, the application should avoid incorporating user-controllable data into redirection targets. In many cases, this behavior can be avoided in two ways: Remove the redirection function from the application, and replace links to it with direct links to the relevant target URLs. Maintain a server-side list of all URLs that are permitted for redirection. Instead of passing the target URL as a parameter to the redirector, pass an index into this list.

Vulnerable URL: https://wakatime.com/settings/account?apikeyrefresh=true

Payload: " X-Forwarded-Host: bing.com "

How to reproduce this vulnerability:

1. Open this URL " https://wakatime.com/settings/account?apikeyrefresh=true " and send it to the repeater in burp suite.
2. add the payload to the header request and forward the request.
3. It will directly redirect to bing.com

Impact

Impact: Whenever a user visits this URL, it will redirect them to site.com. It is used in phishing attacks.
