An un-authenticated attacker could exploit the vulnerability by sending a specially crafted request to an affected ADFS server.\nThe attacker who successfully exploited the vulnerability could then perform cross-site scripting attacks on affected systems and run scripts in the security context of the current user.\nThis security update addresses the vulnerability by ensuring that ADFS properly sanitizes user inputs.",
