CVE-2018-6510
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 · uneditedA cross-site scripting vulnerability in Puppet Enterprise Console of Puppet Enterprise allows a user to inject scripts into the Puppet Enterprise Console when using the Orchestrator. Affected releases are Puppet Puppet Enterprise: 2017.3.x versions prior to 2017.3.6.
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 confidenceA cross-site scripting (XSS) vulnerability exists in the Puppet Enterprise Console web interface. When users interact with the Orchestrator functionality, malicious scripts can be injected into the console, allowing attackers to execute arbitrary JavaScript in the context of other users' sessions.

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 Puppet Enterprise installationRun 'puppet --version' or check for /opt/puppetlabs directory to confirm Puppet Enterprise is installedAffected if Puppet Enterprise is not installed - this CVE does not apply
-
Determine installed Puppet Enterprise versionRun 'puppet-enterprise --version' or check /opt/puppetlabs/etc/puppet-enterprise-version on the console nodeAffected if Cannot determine version - further investigation needed
-
Compare version against affected rangeCheck if installed version is less than 2017.3.6. Compare your version number to this threshold.Affected if Installed version is 2017.3.5 or earlier - environment is potentially affected
-
Verify Console web interface is accessibleAttempt to access the Puppet Enterprise Console at https://<hostname> using the configured port (default 443). Check if the console responds.Affected if Console is not accessible - vulnerability may not be exploitable but the vulnerable code may still be present
-
Check if Orchestrator functionality is enabledReview the Console configuration or check if 'orchestrator' services are running. Look for /opt/puppetlabs/orchestrator directory or check service status with 'puppet-enterprise services status'.Affected if Orchestrator is not configured or used - potential exposure is reduced but vulnerable code may still exist in the installation
If Puppet Enterprise version is confirmed to be lower than 2017.3.6 AND the Console web interface is accessible, the environment is affected by this XSS vulnerability.
