Doc Text:	A flaw was found in Jenkins Pipeline. In the Declarative plugin, the script sandbox protection could be circumvented during the script compilation phase by applying AST. Both the pipeline validation REST APIs and the actual script/pipeline execution are affected. This allows users with Overall/Read permissions, or those able to control Jenkinsfile or the sandboxed Pipeline shared library contents in SCM, to bypass sandbox protection and execute arbitrary code on the Jenkins master. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.	Story Points:	---

Description Paul Harvey 2019-01-25 14:09:59 UTC

A flaw was found in Pipeline: Declarative Plugin before version 1.3.4.1, Pipeline: Groovy Plugin before version 2.61.1 and Script Security Plugin before version 1.50. Script Security sandbox protection could be circumvented during the script compilation phase by applying AST transforming annotations such as @Grab to source code elements. Both the pipeline validation REST APIs and actual script/pipeline execution are affected. This allowed users with Overall/Read permission, or able to control Jenkinsfile or sandboxed Pipeline shared library contents in SCM, to bypass the sandbox protection and execute arbitrary code on the Jenkins master.

Comment 3 Paul Harvey 2019-01-31 06:28:37 UTC

openshift-enterprise-3.2: affected
- containers/openshift-jenkins:rhaos-3.2-rhel-7 in contrib/openshift/base-plugins.txt contains hits for script-security:1.19, workflow-cps:2.6

openshift-enterprise-3.3: affected
- containers/openshift-jenkins:rhaos-3.3-rhel-7 in contrib/openshift/base-plugins.txt contains hits for script-security:1.19, workflow-cps:2.6
- containers/openshift-jenkins-2:rhaos-3.3-rhel-7 in contrib/openshift/base-plugins.txt contains hits for script-security:1.19, workflow-cps:2.6

Once openshift3/jenkins-1-rhel7 and openshift3/jenkins-2-rhel7 container images have been released with these fixes, users of all versions of openshift-enterprise-3.2+ are encouraged to update these container images in their environment.
