CVE-2018-1000058
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 · uneditedJenkins Pipeline: Supporting APIs Plugin 2.17 and earlier have an arbitrary code execution due to incomplete sandbox protection: Methods related to Java deserialization like readResolve implemented 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 confidenceThe Jenkins Pipeline: Supporting APIs Plugin versions 2.17 and earlier fails to properly sandbox Java deserialization methods (such as readResolve) implemented in Pipeline scripts. Since these methods bypass sandbox protection, authenticated users with Pipeline configuration permissions can execute arbitrary code on the Jenkins master.

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.
-
Locate the Pipeline: Supporting APIs PluginIn the Jenkins web UI, go to Manage Jenkins > Manage Plugins > Installed tab. Search for 'Pipeline: Supporting APIs' in the list of installed plugins.Affected if The plugin is not installed, the vulnerability does not apply.
-
Determine the installed versionIn the plugin list, note the version number displayed next to 'Pipeline: Supporting APIs'. Compare this version to 2.17 - versions 2.17 and earlier are affected.Affected if The installed version is 2.17 or earlier.
-
Verify Pipeline functionality is in useCheck if any Pipeline jobs (Jenkinsfile-based jobs) exist in the Jenkins instance. Look for jobs using the 'Pipeline' job type in the Jenkins web UI under 'New Item'.Affected if No Pipeline jobs are configured, the specific attack surface may be limited.
-
Review Pipeline configuration permissionsGo to Manage Jenkins > Configure Global Security. Under 'Authorization', identify which users or groups have 'Pipeline' or 'Job/Configure' permissions. Users with these permissions can configure Pipeline scripts.Affected if There are authenticated users granted Pipeline configuration or Job/Configure permissions beyond administrators.
If the Pipeline: Supporting APIs Plugin is installed at version 2.17 or earlier and authenticated users have Pipeline configuration permissions, the environment is affected by this CVE.

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 dataUpgrade the Jenkins Pipeline: Supporting APIs Plugin to version 2.18 or later. Additionally, limit Pipeline configuration permissions to trusted users only and review all Jenkinsfiles in repositories.
