CVE-2023-39415Known exploitationNetwork attack vector

Unauthenticated Control Panel access via exposed handlers

Published Aug 18, 2023 · Updated Oct 8, 2024

Improper authentication in North Grid Proself affected editions allows remote attackers to access the Control Panel without credentials. The downloadhistory.xml and setclustermyid.xml process definitions expose administrative handler URLs without enforcing administrator authentication. Network access to either handler is sufficient, and the documented consequence is unauthorized access to stored files rather than service interruption.
