Description

A confused deputy vulnerability exists in Jenkins Publisher Over CIFS Plugin 0.10 and earlier in CifsPublisherPluginDescriptor.java that allows attackers to have Jenkins connect to an attacker specified CIFS server with attacker specified credentials. Additionally, this form validation method did not require POST requests, resulting in a CSRF vulnerability. As of version 0.11, this form validation method requires POST requests and Overall/Administer permissions.

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:publish-over-cifs, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.plugins:publish-over-cifs to 0.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2018-1999038 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.
