Active Directory Federation Services (AD FS) Spoofing Vulnerability
Improper verification of cryptographic signature in Active Directory Federation Services (AD FS) allows an unauthorized attacker to perform spoofing over a network.
FAQ
How could an attacker exploit this vulnerability?
An unauthenticated attacker could relay a validly signed SAML response intended for a different endpoint to an affected AD FS endpoint. Successful exploitation could allow the attacker to create an unauthorized session and obtain tokens. No user interaction is required.
