Netmaker: Denial of Service via Server Shutdown Endpoint

Published Mar 7, 2026

Modified 1 weeks ago

Details

Netmaker makes networks with WireGuard. Prior to version 1.2.0, the /api/server/shutdown endpoint allows termination of the Netmaker server process via syscall.SIGINT. This allows any user to repeatedly shut down the server, causing cyclic denial of service with approximately 3-second restart intervals. This issue has been patched in version 1.2.0.
