CVE-2022-3774Public exploitNetwork attack vector

Schedule deletion via attacker-controlled object identifier

Published Oct 31, 2022 · Updated Apr 15, 2025

Improper resource authorization in SourceCodester Train Scheduler App 1.0 allows remote authenticated users to delete schedule records. The delete action accepts the id request parameter as a schedule-record identifier and deletes the referenced record without an object-level authorization check. A valid low-privilege session can therefore remove another schedule record and disrupt the published timetable.
