Attackers can authenticate to the admin console using default credentials, upload a malicious Java archive as a web service, and execute arbitrary commands on the host via SOAP requests to the deployed service."

Los atacantes pueden autenticarse en la consola de administración utilizando credenciales predeterminadas, cargar un archivo Java malicioso como un servicio web y ejecutar comandos arbitrarios en el host a través de solicitudes SOAP al servicio desplegado."
