CVE-2020-15412Network attack vector

Unauthorized event contact via missing ACL check

Published Jun 30, 2020 · Updated Aug 4, 2024

Missing authorization in MISP 2.4.128 allows remote authenticated users to send contact requests for events they cannot access. EventsController::contact() checked only whether a supplied event identifier existed instead of fetching the event through the requesting user's ACL. A valid MISP account and an inaccessible event identifier are required; the action sends an event contact email without granting event visibility.
