CVE-2017-1000088
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 · uneditedThe Sidebar Link plugin allows users able to configure jobs, views, and agents to add entries to the sidebar of these objects. There was no input validation, which meant users were able to use javascript: schemes for these links.
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 Sidebar Link plugin for Jenkins allowed users with job/view/agent configuration permissions to inject JavaScript code via javascript: URLs in sidebar links due to missing input validation. This stored XSS vulnerability allowed malicious links to execute in the browsers of other users viewing the affected sidebar entries.

dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Sidebar Link plugin is installedGo to Manage Jenkins > Manage Plugins > Installed tab and look for 'Sidebar Link' in the list, or check the $JENKINS_HOME/plugins directory for the sidebar-link plugin folderAffected if The plugin is present in the plugin list or file system
-
Check the installed version of Sidebar Link pluginIn Manage Jenkins > Manage Plugins > Installed, find the Sidebar Link plugin and read the Version column; compare against the affected range (versions <= 1.8)Affected if The installed version number is 1.8 or lower
-
Identify configured sidebar links in jobsReview job configurations: for each job, go to Configure > Sidebar Links section and inspect any defined links for their URL valuesAffected if Any sidebar link URL contains 'javascript:' or other potentially dangerous URL schemes (e.g., data:, vbscript:)
-
Identify configured sidebar links in views and agentsReview view configurations (Manage Jenkins > Manage Views > configure) and agent configurations (manage each agent) for any sidebar links with unvalidated URL fieldsAffected if Any view or agent sidebar link URLs contain 'javascript:' or similar dangerous schemes
-
Check which users have permission to configure sidebar linksReview Jenkins authorization matrix or role-based access control settings to determine which users or groups have Job/View/Agent Configure permissionsAffected if Users with elevated or broad configuration permissions exist and the plugin is installed and vulnerable

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 a patched version of the Sidebar Link plugin that implements URL scheme validation (rejecting javascript: and other dangerous schemes), or restrict configuration permissions until the patch can be applied.
