Description

A arbitrary file write vulnerability exists in Jenkins Fortify CloudScan Plugin 1.5.1 and earlier in ArchiveUtil.java that allows attackers able to control rulepack zip file contents to overwrite any file on the Jenkins master file system, only limited by the permissions of the user the Jenkins master process is running as.

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:fortify-cloudscan-jenkins-plugin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.plugins:fortify-cloudscan-jenkins-plugin to 1.5.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2018-1000607 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.
