CVE-2020-2261
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 Perfecto Plugin 1.17 and earlier executes a command on the Jenkins controller, allowing attackers with Job/Configure permission to run arbitrary commands on the Jenkins controller
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 Perfecto Plugin versions 1.17 and earlier contains a command injection vulnerability where authenticated users with Job/Configure permission can execute arbitrary OS commands on the Jenkins controller by manipulating plugin configuration parameters.

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.
-
Verify Perfecto plugin installationNavigate to Jenkins > Manage Jenkins > Manage Plugins > Installed tab, or use the Jenkins script console: jenkins.model.Jenkins.getInstance().getPluginManager().getPlugin('perfecto').getWrapper().getVersion()Affected if Perfecto plugin is present in the installed plugins list
-
Determine installed Perfecto plugin versionIn Manage Plugins > Installed tab, locate Perfecto in the list and note the Version column. Alternatively, check the file: $JENKINS_HOME/plugins/perfecto/META-INF/MANIFEST.MF for the Plugin-Version attributeAffected if Version is 1.17 or earlier (e.g., 1.17, 1.16, 1.15, etc.)
-
Confirm plugin is actually in useSearch job configurations for Perfecto-related build steps: check $JENKINS_HOME/jobs/*/config.xml for <perfecto> XML elements, or review job configurations via UI for Perfecto Cloud Media or Perfecto Mobile Cloud build stepsAffected if Any job is configured to use Perfecto plugin features
-
Review Job/Configure permission assignmentsNavigate to Manage Jenkins > Manage Users > Security, or check $JENKINS_HOME/users/*/config.xml for roles/permissions. In matrix-based authorization, verify which users or groups have the Job/Configure permission enabledAffected if Any user or group other than administrators has Job/Configure permission granted
The environment is affected if the Perfecto plugin is installed at version 1.17 or earlier, regardless of whether it is actively used in any job configuration.

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 to Perfecto Plugin version 1.18 or later. If an update is unavailable, disable or remove the plugin. Review and restrict Job/Configure permissions to minimize attack surface.
