Security readout for executives and security teams
Plain-English summary
This issue lets a Jenkins user with basic Overall/Read access view some Gerrit configuration information from the Gerrit Trigger Plugin. It is not described as remote unauthenticated compromise, but exposed CI/CD integration details can still aid follow-on attacks or reveal sensitive operational configuration.
Executive priority
Treat as a targeted CI/CD information exposure issue. Prioritize remediation where Jenkins access is broad, externally reachable, or tied to sensitive Gerrit repositories, but current sources do not support emergency active-exploitation handling.
Technical view
CVE-2018-1000105 is an improper authorization issue in Jenkins Gerrit Trigger Plugin 2.27.4 and earlier, involving GerritManagement.java, GerritServer.java, and PluginImpl.java. The published description says users with Overall/Read permission can retrieve some Gerrit configuration information from Jenkins.
Likely exposure
Exposure is limited to Jenkins environments using Gerrit Trigger Plugin 2.27.4 or earlier where untrusted or broadly scoped users have Overall/Read access.
Exploitation context
The source bundle does not identify active exploitation, public exploit availability, CVSS scoring, or KEV listing. Exploitation requires at least Overall/Read access to Jenkins, based on the CVE description.
Researcher notes
Available evidence is narrow: affected component, authorization condition, and impact are stated, but CVSS, CWE, exploit status, and fixed-version details are absent from the supplied bundle. Do not assume credential disclosure unless confirmed in Jenkins guidance.
Mitigation direction
- Inventory Jenkins instances using Gerrit Trigger Plugin.
- Identify plugin versions at or below 2.27.4.
- Review the Jenkins advisory for the vendor-corrected version or mitigation.
- Restrict Overall/Read access to trusted users only.
- Review Gerrit integration settings for unnecessary exposed secrets or details.
Validation and detection
- Check Jenkins plugin inventory for Gerrit Trigger Plugin version.
- Confirm whether any instance runs version 2.27.4 or earlier.
- Review Jenkins permissions for users granted Overall/Read.
- Check audit logs for unusual Gerrit configuration access, if available.
- Verify remediation against the Jenkins advisory after changes.
