CVE-2023-0566Network attack vector

Stored script execution via unvalidated cron interval

Published Jan 29, 2023 · Updated Mar 28, 2025

Stored cross-site scripting in Froxlor before 2.0.10 allows remote authenticated users to execute script in an administrator's browser. Cronjobs.update accepts an arbitrary interval_interval value and stores it for later rendering instead of restricting it to the five documented interval units. Administrative API access is required to plant the value, and another administrator must view the affected cron-job interface for script execution.
