A flaw was found in JBoss EAP, where the authentication configuration is set-up using a legacy SecurityRealm, to delegate to a legacy PicketBox SecurityDomain, and then reloaded to admin-only mode. This flaw allows an attacker to perform a complete authentication bypass by using an arbitrary user and password. The highest threat to vulnerability is to system availability.
