CVE-2022-42992Public exploitNetwork attack vector

Stored script execution via unsanitized schedule fields

Published Oct 27, 2022 · Updated Jul 9, 2026

Stored XSS in Train Scheduler App 1.0 allows remote authenticated users to execute scripts in another user's browser via schedule fields. The application stores Train Code, Train Name, and Destination values without neutralizing script markup, then renders the saved payload when the affected schedule is viewed. Exploitation requires access to add or edit a schedule and a separate user to view the poisoned entry; the script can read or alter data available to that browser session.
