Jenkins Deserialization of Untrusted Data Vulnerability - CVE-2017-1000353

Critical
Reference: CVE-2017-1000353
NVD Link: https://nvd.nist.gov/vuln/detail/CVE-2017-1000353
Title: Jenkins Deserialization of Untrusted Data Vulnerability
Overview:

Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to an unauthenticated remote code execution. An unauthenticated remote code execution vulnerability allowed attackers to transfer a serialized Java SignedObject object to the Jenkins CLI that would be deserialized using a new ObjectInputStream bypassing the existing blacklist-based protection mechanism. We39re fixing this issue by adding SignedObject to the blacklist. We39re also backporting the new HTTP CLI protocol from Jenkins 2.54 to LTS 2.46.2 and deprecating the remoting-based (i.e. Java serialization) CLI protocol disabling it by default.
