Security readout for executives and security teams
Plain-English summary
This flaw affects Jenkins Fortify CloudScan Plugin 1.5.1 and earlier. If an attacker can control the contents of a rulepack zip file processed by the plugin, they may overwrite files on the Jenkins master host within the Jenkins process permissions. That can threaten build integrity and CI availability.
Executive priority
Treat this as high priority if affected Jenkins controllers support production builds or deployment pipelines. The business risk is unauthorized modification of CI server files, which can undermine software delivery trust even without confirmed public exploitation.
Technical view
CVE-2018-1000607 is an arbitrary file write issue in ArchiveUtil.java in Jenkins Fortify CloudScan Plugin 1.5.1 and earlier. The vulnerable behavior allows rulepack zip contents to write outside intended locations on the Jenkins master file system, constrained by the operating-system privileges of the Jenkins master process.
Likely exposure
Exposure is limited to Jenkins environments using Fortify CloudScan Plugin 1.5.1 or earlier, especially where untrusted or low-trust users can influence rulepack zip contents.
Exploitation context
The provided sources do not show active exploitation, and the CVE is not listed as KEV. Exploitation requires attacker control over rulepack zip contents processed by the plugin, so access paths and plugin workflow permissions determine practical risk.
Researcher notes
Evidence is concise but clear on impact and prerequisite: attacker-controlled rulepack zip contents can overwrite arbitrary Jenkins master files within process permissions. No CVSS, CWE, exploit status, or fixed version is included in the supplied bundle, so remediation should be tied to Jenkins SECURITY-870.
Mitigation direction
- Identify Jenkins instances using Fortify CloudScan Plugin 1.5.1 or earlier.
- Review Jenkins SECURITY-870 and apply the vendor-recommended update or mitigation.
- Disable or remove the plugin where it is not operationally required.
- Restrict rulepack zip submission or control to trusted administrators.
- Run Jenkins master with the least file-system permissions practical.
Validation and detection
- Check installed Jenkins plugin inventory for Fortify CloudScan Plugin version.
- Review who can create, upload, or modify rulepack zip contents.
- Inspect Jenkins master file permissions for sensitive writable paths.
- Review recent Jenkins changes for unexpected overwritten configuration or job files.
- Confirm vendor guidance has been applied across all Jenkins controllers.
