Description:

A remote attacker can hijack a KDC connection using a spoofed AS-REP response. For an APM access policy configured with AD authentication and SSO (single sign-on) agent, if a spoofed credential related to this vulnerability is used, depending how the back-end system validates the authentication token it receives, access will most likely fail. An APM access policy can also be configured for BIG-IP system authentication. A spoofed credential related to this vulnerability for an administrative user through the APM access policy results in local administrative access.'
