Unauthenticated Configuration Reconfiguration in ChronoFrame

Executive Summary

ChronoFrame through 1.0.0 has a missing authentication vulnerability in the server/api/wizard/ handlers. Unauthenticated attackers can reconfigure already configured instances by sending POST requests to /api/wizard/storage. This allows them to activate an attacker-controlled S3 or OpenList provider, redirecting uploads and storage reads, and overwrite site and map settings.
