Security readout for executives and security teams
Plain-English summary
This Jenkins plugin issue could let a low-privileged Jenkins user abuse stored credentials by making Jenkins contact a URL they control. The main business risk is theft of Jenkins-held secrets, which may include credentials for source code, CI/CD systems, or third-party services.
Executive priority
Treat this as a high-priority CI/CD secret exposure risk if the plugin is present. Prioritize inventory, access review, and vendor-guided remediation before broader hardening work.
Technical view
CVE-2018-1000191 affects Jenkins Black Duck Detect Plugin 1.4.0 and older. Attackers with Overall/Read access can specify a URL and credentials IDs obtained separately, causing Jenkins to connect in a way that may expose stored credentials. The source bundle provides no CVSS, CWE, or fixed version.
Likely exposure
Exposure is limited to Jenkins environments with Black Duck Detect Plugin 1.4.0 or older installed, especially where non-administrators have Overall/Read access and credentials are stored in Jenkins.
Exploitation context
The bundle does not show KEV listing or active exploitation evidence. Exploitation requires Jenkins Overall/Read access plus knowledge of valid credentials IDs from another method. The likely impact is credential capture, not direct unauthenticated compromise.
Researcher notes
The key security boundary is Jenkins Overall/Read access combined with credential ID knowledge. Evidence is incomplete on scoring and fixed versions in the provided bundle, so validation should stay tied to Jenkins advisory SECURITY-866 and local plugin inventory.
Mitigation direction
- Check Jenkins vendor guidance for the corrected plugin version or configuration advice.
- Upgrade, disable, or remove the affected plugin according to Jenkins guidance.
- Restrict Overall/Read access to trusted users only.
- Rotate Jenkins credentials if misuse or exposure is suspected.
- Review credential storage and remove secrets no longer required.
Validation and detection
- Inventory Jenkins controllers for Black Duck Detect Plugin 1.4.0 or older.
- Review Jenkins permissions for users with Overall/Read access.
- Check whether sensitive credentials are stored in Jenkins and used by this plugin.
- Audit logs for unexpected outbound connections from Jenkins around plugin usage.
- Confirm remediation against Jenkins advisory SECURITY-866.
