Microsoft ADFS 4.0 Windows Server 2016 and previous (Active Directory Federation Services) has an SSRF vulnerability via the txtBoxEmail parameter in /adfs/ls.
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
