Appin Microsoft Hall of Fame


Today i’m going to share my journey how i got this bug in one of the Microsoft owned domain.

Vulnerable Domain: https://www.healthvault.com/en-us

Vulnerability: “Open Redirect Vulnerability”

So my journey start to finding this bug as i just stumble upon https://www.healthvault.com/en-us and try to find out some Vulnerability on that domain.

First I login on https://www.healthvault.com/en-us with a valid credentials and goto Basic Profile section, where we can make changes in our profile. There’s a cancel link and this is the Vulnerable link for Open Redirect where Cancel Record with referrer parameter have “Open Redirect” Flaw https://account.healthvault.co.uk/Record/Cancel?referrer=%2f%2fwww.google.co.in

that redirect on other website, in the end it will redirect to www.google.co.in

thus , showing a redirection bug that is considered as very critical because it may be use for Phishing or redirect user to any Malicious Website.

I’m going to share a video POC so that Reader can understand in better way

I’ll Share more information & Tutorials about Open Redirect Vulnerability in my upcoming post.

Stay with Us & Thanks
