Security readout for executives and security teams
Plain-English summary
CVE-2018-1000106 lets a Jenkins user with only Overall/Read access change Gerrit Trigger Plugin configuration. That can undermine CI/CD governance by allowing unauthorized changes to how Jenkins integrates with Gerrit. The source bundle does not provide CVSS, confirmed exploitation, or a named fixed version.
Executive priority
Treat as a targeted CI/CD governance issue. It is not documented as actively exploited, but unauthorized Gerrit configuration changes could affect build integrity and release control. Prioritize exposed or broadly accessible Jenkins environments.
Technical view
The vulnerability is improper authorization in Jenkins Gerrit Trigger Plugin 2.27.4 and earlier, affecting GerritManagement.java, GerritServer.java, and PluginImpl.java. An authenticated attacker with Overall/Read permission can modify Gerrit configuration in Jenkins. Source evidence does not specify exploit details, patch version, CWE, or CVSS.
Likely exposure
Exposure is limited to Jenkins instances using Gerrit Trigger Plugin 2.27.4 or earlier, especially where many users have Overall/Read access. Publicly reachable Jenkins controllers or broad internal read access increase risk.
Exploitation context
The provided sources do not indicate active exploitation, KEV listing, or public exploit availability. The attacker must already have Jenkins Overall/Read access, making this primarily an authenticated authorization bypass risk.
Researcher notes
Evidence is limited to the CVE description and Jenkins SECURITY-403 reference. Do not assume unauthenticated access, affected products beyond Jenkins Gerrit Trigger Plugin, exploit maturity, or a specific fixed version without reviewing vendor advisory details.
Mitigation direction
- Inventory Jenkins instances using Gerrit Trigger Plugin.
- Prioritize instances running plugin version 2.27.4 or earlier.
- Check the Jenkins advisory for vendor-approved upgrade or mitigation guidance.
- Restrict Jenkins Overall/Read access to trusted users where possible.
- Review Gerrit integration configuration for unauthorized changes.
Validation and detection
- Confirm installed Gerrit Trigger Plugin versions on Jenkins controllers.
- Review Jenkins permission assignments for Overall/Read access.
- Audit recent Gerrit Trigger Plugin configuration changes.
- Check Jenkins security advisory SECURITY-403 for remediation status.
- Look for unexpected Gerrit server or trigger configuration changes.
