CVE-2015-5317: Jenkins UI Information Disclosure Vulnerability Exposes Job and Build Names
What It Is — The Jenkins User Interface leaks the names of jobs and builds on the “Fingerprints” pages to anyone who can view the page, even if they lack permission to see those resources.
Exploitability — No authentication is required to view the page; the flaw is publicly known and has a CVSS v3 score of 5.3 (moderate).
Affected Products — All Jenkins server installations that have not applied the vendor‑released patch (versions prior to the fix released in 2015).
Why It Matters for Trust & Control Assurance
- Access‑control assurance: The vulnerability shows a gap in enforcing least‑privilege UI segregation, a core control objective across most governance frameworks.
- Defensible audit evidence: If job names are exposed, logs may not capture the unauthorized view, weakening the audit trail that regulators and auditors expect.
- Continuous monitoring need: Detecting such UI‑level leaks requires ongoing control monitoring rather than one‑off scans, reinforcing the demand for real‑time evidence of compliance posture.
Recommended Actions
- Patch immediately – Apply the Jenkins security update that restricts the Fingerprints page to authorized users.
- Enforce authentication – Require strong authentication (e.g., SSO, MFA) for all UI access.
- Review and tighten UI permissions – Audit role‑based access controls to ensure users only see resources they are entitled to.
- Enable detailed logging – Capture UI access events and retain logs for audit purposes.
- Map to your access‑control control objective – Document remediation as evidence for frameworks such as NIST CSF 2.0.
