<p>A security feature bypass vulnerability exists when ADFS incorrectly treats requests coming from Extranet clients as Intranet requests. To exploit this vulnerability, an attacker could run a specially crafted application and attempt to brute-force an account password. An attacker who successfully exploited this vulnerability could bypass the account lockout protection enforced on Extranet client requests.</p> <p>This update corrects the security feature’s behavior by correcting how ADFS processes requests.</p>
