Description

A exposure of sensitive information vulnerability exists in Jenkins z/OS Connector Plugin 1.2.6.1 and earlier in SCLMSCM.java that allows an attacker with local file system access or control of a Jenkins administrator's web browser (e.g. malicious extension) to retrieve the configured password. IBM z/OS Connector Plugin 2.0.0 and newer integrates with Credentials Plugin, no longer storing credentials itself.

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

  2. Fix

    Update org.jenkins-ci.plugins:zos-connector to 2.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2018-1000608 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.
