Description

A vulnerability in the GenericAdminAuthenticator component of Azul Payara Server and Azul Payara Micro allows a remote, unauthenticated attacker to bypass JMX/RMI administrative access restrictions by spoofing the client host address. Successful exploitation can grant administrative access to the MBean server and lead to remote code execution. Azul Payara Micro is affected only when its JMX connector is enabled.
