Description

Jenkins Oracle Cloud Infrastructure Compute Plugin 1.0.16 and earlier does not perform SSH host key validation when connecting to OCI clouds.

This lack of validation could be abused using a man-in-the-middle attack to intercept these connections to OCI clouds.

Oracle Cloud Infrastructure Compute Plugin 1.0.17 provides strategies for performing host key validation for administrators to select the one that meets their security needs.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:oracle-cloud-infrastructure-compute, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.plugins:oracle-cloud-infrastructure-compute to 1.0.17 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-37948 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
