Security readout for executives and security teams
Plain-English summary
This Jenkins plugin flaw lets a user who can configure jobs or nodes change ownership metadata even if they lack ownership-specific permissions. That could weaken governance, accountability, or control workflows around Jenkins resources. The source bundle does not provide CVSS, confirmed exploitation, or a named fixed version.
Executive priority
Treat as a governance and CI control integrity issue, not a broad remote compromise based on current evidence. Prioritize Jenkins systems supporting production deployments or regulated change-control processes.
Technical view
CVE-2018-1000107 affects Jenkins Job and Node Ownership Plugin 0.11.0 and earlier. Improper authorization in OwnershipDescription.java, JobOwnerJobProperty.java, and OwnerNodeProperty.java allows users with Job/Configure or Computer/Configure permission to override ownership metadata without Ownership permissions.
Likely exposure
Exposure is limited to Jenkins environments using Job and Node Ownership Plugin 0.11.0 or earlier, especially where non-admin users have Job/Configure or Computer/Configure permissions.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation evidence. Abuse requires an account with Jenkins job or computer configuration permissions, so likely scenarios include insider misuse or compromised privileged CI accounts.
Researcher notes
The CVE record identifies the authorization boundary and affected plugin version range, but the provided data lacks CVSS, CWE, exploit evidence, and exact remediation details. Validate against Jenkins advisory SECURITY-498 before asserting fix versions.
Mitigation direction
- Inventory Jenkins instances for Job and Node Ownership Plugin usage and version.
- Review Jenkins advisory SECURITY-498 for vendor-approved fix or mitigation guidance.
- Restrict Job/Configure and Computer/Configure permissions to trusted administrative users.
- Review ownership metadata on sensitive jobs and nodes for unexpected changes.
- Update or replace the plugin according to Jenkins vendor guidance.
Validation and detection
- Confirm whether any Jenkins instance runs plugin version 0.11.0 or earlier.
- Review role assignments granting Job/Configure or Computer/Configure permissions.
- Check audit or configuration history for ownership changes by unexpected users.
- Verify post-remediation ownership changes require the intended Ownership permissions.
- Document affected instances, permission findings, and remediation status.
