Summary
The single sign-on implementation in Active Directory Federation Services (ADFS) in Microsoft Windows Server 2003 SP2 and Server 2008 Gold and SP2 does not properly remove credentials at the end of a network session, which allows physically proximate attackers to obtain the credentials of a previous user of the same web browser by using data from the browser's cache, aka "Single Sign On Spoofing in ADFS Vulnerability."
Exploit prediction
1.26% chance of exploitation in the next 30 days, higher than 69% of all scored CVEs (FIRST EPSS, 2026-11-08).
