First published: Wed Nov 09 2022(Updated: )
A flaw was found in the Eclipse Californium Scandium package. This issue occurs when failing handshakes don't clean up counters for throttling, causing the threshold to be reached without being released again, resulting in a denial of service. An attacker could submit a high quantity of server requests, leaving the server unable to respond.
