Vulnerability description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to lack of serialized object validation. A remote attacker can transfer a serialized Java SignedObject object to the remoting-based Jenkins CLI, deserialize it using a new ObjectInputStream, bypass the existing blacklist-based protection mechanism, inject arbitrary commands and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
