Description

There exists a Java object deserialization vulnerability
in multiple versions of WebLogic.

Unauthenticated remote code execution can be achieved by
sending a serialized `BadAttributeValueExpException`
object over the T3 protocol to vulnerable versions of
WebLogic. Leveraging an `ExtractorComparator` enables
the ability to trigger `method.invoke()`, which will
execute arbitrary code.
