23
          Unauthenticated remote code execution can be achieved by

24
          sending a serialized `BadAttributeValueExpException`

          object over the T3 protocol to vulnerable versions of

26
          WebLogic. Leveraging an `ExtractorComparator` enables

27
          the ability to trigger `method.invoke()`, which will

28
          execute arbitrary code.
