Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Incorrect access control in the component /iclock/Settings?restartNCS=1 of NovaCHRON Zeitsysteme GmbH & Co. KG Smart Time Plus v8.x to v8.6 allows attackers to arbitrarily restart the NCServiceManger via a crafted GET request.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Incorrect access control in NovaCHRON Smart Time Plus allows unauthenticated attackers to restart the NCServiceManager service via a crafted GET request to /iclock/Settings?restartNCS=1. The endpoint lacks proper authorization checks, enabling any user to trigger a critical service restart.

MitigationImplement proper authentication and authorization for the /iclock/Settings endpoint. Require authenticated sessions and role-based access control for service management operations. Consider changing the restart action from GET to POST with CSRF protection.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify NovaCHRON Smart Time Plus installation
    Locate the application installation directory or check running services for NCServiceManager or NovaCHRON components
    Affected if The product is installed and the NCServiceManager service exists on the system
  2. Verify web interface accessibility
    Check if the application exposes an HTTP/HTTPS interface on expected ports (commonly 80, 443, or 8080). Use browser or curl to access the /iclock/ path
    Affected if The web interface is reachable over the network
  3. Test unauthenticated endpoint access
    Send a GET request to http://[host]/iclock/Settings without providing any authentication credentials. Use curl -v or similar tool
    Affected if The request returns a successful HTTP response (200) rather than requiring login (401/403/redirect to login)
  4. Confirm restart parameter vulnerability
    Send a crafted GET request to http://[host]/iclock/Settings?restartNCS=1 without any authentication. Observe if the NCServiceManager service restarts or if the request succeeds
    Affected if The request completes without authentication and the service restarts or returns success without authorization error
  5. Review service logs for unauthorized restarts
    Examine application and system logs for NCServiceManager restart events that occurred without corresponding authenticated administrative actions
    Affected if Service restarts appear in logs without associated authenticated user sessions

A defender is affected if NovaCHRON Smart Time Plus is installed and the /iclock/Settings?restartNCS=1 endpoint accepts requests without requiring authentication, allowing unauthorized service restarts.
