Summary: This security update resolves a vulnerability in Microsoft Active Directory Federation Services (AD FS). The vulnerability could allow elevation of privilege if an attacker submits a specially crafted URL to a target site that, due to the vulnerability, fails to properly sanitize script embedded in the URL.
