Description
An unauthenticated Java object deserialization vulnerability exists
in the CLI component for Jenkins versions `v2.56` and below.
The `readFrom` method within the `Command` class in the Jenkins
CLI remoting component deserializes objects received from clients without
first checking / sanitizing the data. Because of this, a malicious serialized
object contained within a serialized `SignedObject` can be sent to the Jenkins
endpoint to achieve code execution on the target.
