CVE-2015-8103 is a remote code execution vulnerability in the Jenkins CLI subsystem affecting Jenkins before 1.638 and Jenkins LTS before 1.625.2. The flaw arises from deserialization of attacker-controlled Java objects in the CLI handling path. In vulnerable deployments, the presence of a commons-collections library gadget chain enables exploitation through a crafted serialized object, including known gadget variants such as the Groovy-based ysoserial chain. Successful exploitation causes arbitrary code to execute within the Jenkins process context.
