CVE-2017-1000096
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedArbitrary code execution due to incomplete sandbox protection: Constructors, instance variable initializers, and instance initializers in Pipeline scripts were not subject to sandbox protection, and could therefore execute arbitrary code. This could be exploited e.g. by regular Jenkins users with the permission to configure Pipelines in Jenkins, or by trusted committers to repositories containing Jenkinsfiles.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceJenkins Pipeline scripts had a sandbox bypass vulnerability where constructors, instance variable initializers, and instance initializers were not subject to sandbox protection, allowing arbitrary code execution by users with Pipeline configuration permissions or trusted committers with Jenkinsfiles.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Jenkins Pipeline plugin versionNavigate to Jenkins > Manage Jenkins > Manage Plugins > Installed tab, or check the plugin file metadata at /var/lib/jenkins/plugins/pipeline*.json, or run: jenkins-cli.jar plugins -pipelineAffected if Pipeline plugin version is 2.36 or lower
-
Confirm Pipeline plugin is actually installedLook for Pipeline Groovy DSL or Pipeline plugin entry in Manage Jenkins > Manage Plugins > InstalledAffected if Pipeline plugin is present in the Jenkins installation
-
Check for users with Pipeline configuration permissionsNavigate to Jenkins > Manage Jenkins > Configure Global Security > Authorization matrix, or review job-based permissions in project-based security settings for Pipeline jobsAffected if Any users or groups have the permission to configure Pipeline scripts (Job/Configure or Job/Build permissions on Pipeline jobs)
-
Identify Pipeline jobs using inline scriptsReview Pipeline job configurations at Jenkins > [Job Name] > Configure, looking for 'Pipeline Script' option rather than 'Pipeline Script from SCM'Affected if Pipeline jobs are configured with inline script definitions that can be edited by users with Job/Configure permission
A user is affected if Jenkins Pipeline plugin version is 2.36 or lower AND either users with Pipeline configuration permissions exist or Jenkinsfiles from untrusted committers are processed.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the Jenkins security update that enforces sandbox protection on these code paths and review Pipeline permissions to ensure only authorized users can configure Pipelines.
