CVE-2017-1000096
Description
The jenkins-plugin-script-security has incomplete sandbox protection which allows attackers to execute arbitrary code via constructors, instance variable initializers, and instance initializers in Pipeline scripts. Exploitation of this requires the attacker to have permission to configure Pipelines in Jenkins or be a trusted committers to repositories containing Jenkinsfiles and for that Jenkins instance to be hosting other projects as well that the attacker should not have access to.
Statement
This issue affects the versions of jenkins-plugin-workflow-cps as shipped with Red Hat OpenShift Enterprise 3. However, this flaw is of low impact under the supported scenarios in OpenShift Enterprise 3. A future update may address this issue.
