CVE-2017-1000093
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 · uneditedPoll SCM Plugin was not requiring requests to its API be sent via POST, thereby opening itself to Cross-Site Request Forgery attacks. This allowed attackers to initiate polling of projects with a known name. While Jenkins in general does not consider polling to be a protection-worthy action as it's similar to cache invalidation, the plugin specifically adds a permission to be able to use this functionality, and this issue undermines that permission.
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 Poll SCM Plugin for Jenkins did not enforce POST requests for its API endpoints, enabling Cross-Site Request Forgery (CSRF) attacks. Attackers could trigger polling of projects with known names by tricking authenticated users into visiting malicious pages, bypassing the plugin's permission system designed to control this functionality.

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 Poll SCM Plugin is installedLog into Jenkins as an administrator, go to Manage Jenkins > Manage Plugins > Installed tab, and search for 'Poll SCM' in the list of installed plugins.Affected if The Poll SCM Plugin appears in the installed plugins list.
-
Check installed Poll SCM Plugin versionIn the Installed plugins tab, locate the Poll SCM Plugin and note the version number displayed in the 'Version' column. Alternatively, run this Groovy script in Manage Jenkins > Script Console: Jenkins.instance.pluginManager.plugins.each { if (it.shortName == 'poll-scm') { println "Poll SCM Version: " + it.version } }Affected if The installed version is 1.3.1 or lower.
-
Verify Jenkins CSRF protection is enabledGo to Manage Jenkins > Configure Global Security > CSRF Protection section. Confirm the 'Enable proxy compatibility' or default 'Prevent Cross Site Request Forgery exploits' checkbox is checked/enabled.Affected if CSRF protection is disabled or not configured.
-
Identify jobs using Poll SCM triggersRun this Groovy script in Manage Jenkins > Script Console: Jenkins.instance.allItems.each { job -> if (job.hasProperty('pollSCM') || (job.triggers.values().any { it.class.name.contains('PollSCMTrigger') })) { println job.fullName } }Affected if Jobs exist that are configured with Poll SCM triggers.
You are affected if the Poll SCM Plugin version is 1.3.1 or lower, CSRF protection is disabled, and jobs using Poll SCM triggers exist in your Jenkins instance.

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 dataUpdate the Poll SCM Plugin to a version that requires POST requests for API calls. Additionally, ensure Jenkins' built-in CSRF protection is enabled.
