Description
OpenAM before 16.1.4 contains a denial of service vulnerability that allows unauthenticated attackers to exhaust server resources by sending serialized Java data without size or structure limits. Attackers can send small crafted requests to remote SDK endpoints, classic login pages, or the administration console to block authentication, session validation and policy decisions.
