Active Directory Federation Services (ADFS) in Microsoft Windows Server 2003 SP2 and Server 2008 Gold and SP2 does not properly validate headers in HTTP requests, which allows remote authenticated users to execute arbitrary code via a crafted request to an IIS web server, aka "Remote Code Execution in ADFS Vulnerability."
Improper Input Validation The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly.
