Security readout for executives and security teams
Plain-English summary
This Jenkins plugin flaw lets any authenticated user with Overall/Read permission view lamp-related job names, MAC addresses, and IP addresses, and rename lamps. It is not described as remote code execution, but it can expose operational details and allow limited unauthorized changes.
Executive priority
Treat as a moderate-priority Jenkins hardening item. Escalate if the affected plugin is installed on shared or externally reachable Jenkins systems, or if job names and device network details are sensitive.
Technical view
CVE-2022-41242 is a CWE-862 missing permission check in Jenkins extreme-feedback Plugin 1.7 and earlier. A network attacker with Overall/Read can access information about configured lamps and alter lamp names. CVSS 3.1 is 5.4: low complexity, privileges required, no user interaction, low confidentiality and integrity impact.
Likely exposure
Exposure is limited to Jenkins environments running extreme-feedback Plugin 1.7 or earlier, especially where Overall/Read is broadly granted. Internet-facing Jenkins instances or shared CI systems with many authenticated users carry higher practical risk.
Exploitation context
The provided sources do not show active exploitation, and CISA KEV status is false. Exploitation requires Jenkins access and Overall/Read permission. The described impact is information disclosure and limited integrity change, not system takeover.
Researcher notes
Evidence supports a permission-check bypass affecting plugin-specific lamp management data and rename actions. Do not infer broader Jenkins compromise, credential theft, or code execution from the provided sources. Patch specifics are not included in the bundle, so confirm current vendor guidance.
Mitigation direction
- Check Jenkins advisory and plugin guidance for fixed versions or vendor remediation.
- Update or remove Jenkins extreme-feedback Plugin if version 1.7 or earlier is installed.
- Restrict Overall/Read permission to trusted users and groups only.
- Disable the plugin if extreme-feedback lamps are not operationally required.
Validation and detection
- Inventory Jenkins controllers for the extreme-feedback Plugin and installed version.
- Review Jenkins authorization matrices for broad Overall/Read assignments.
- Check lamp configuration for exposed job names, MAC addresses, and IP addresses.
- Review audit or access logs for unexpected lamp rename activity.

Missing Authorization
Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
