CVE-2018-1000056
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 JUnit Plugin 1.23 and earlier processes XML external entities in files it parses as part of the build process, allowing attackers with user permissions in Jenkins to extract secrets from the Jenkins master, perform server-side request forgery, or denial-of-service attacks.
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 JUnit Plugin 1.23 and earlier contains an XML External Entity (XXE) vulnerability. The plugin processes XML files without disabling external entity processing, allowing authenticated users to craft malicious XML that can extract secrets from the Jenkins master, perform SSRF attacks against internal services, or cause denial-of-service conditions.

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.
-
Check installed JUnit plugin versionNavigate to Manage Jenkins > Manage Plugins > Installed tab and locate the 'JUnit' plugin, or check the plugin's .jpi file in $JENKINS_HOME/plugins/ for the version manifestAffected if The installed version is 1.23 or earlier
-
Identify jobs using JUnit pluginSearch job configurations for the 'junit' build step or step that publishes test results (look for 'Publish JUnit test result report' in job configs or check for junit() pipeline step in JenkinsfileAffected if Any job is configured to parse JUnit XML result files using this plugin
-
Verify XML files are being processedReview build logs and artifact storage to confirm that XML files from external or untrusted sources are being ingested via the JUnit plugin (check test result XML locations in build workspaces)Affected if The plugin is actively parsing XML files from build outputs or external inputs
You are affected if the JUnit plugin version is 1.23 or earlier AND any Jenkins job is configured to parse XML test results through this plugin.
Generated from the published advisory. Verify against your own 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 JUnit Plugin to version 1.24 or later, which disables XML external entity processing. As an interim measure, disable parsing of untrusted XML files in build pipelines until the upgrade can be applied.
