Vulnerability from variot
In Eclipse Californium version 2.0.0 to 2.7.2 and 3.0.0-3.5.0 a DTLS resumption handshake falls back to a DTLS full handshake on a parameter mismatch without using a HelloVerifyRequest. Especially, if used with certificate based cipher suites, that results in message amplification (DDoS other peers) and high CPU load (DoS own peer). The misbehavior occurs only with DTLS_VERIFY_PEERS_ON_RESUMPTION_THRESHOLD values larger than 0. Eclipse Foundation of Californium Exists in unspecified vulnerabilities.Service operation interruption (DoS) It may be in a state. Eclipse Californium is a Java-based code library that provides Coap backend support for the Internet of Things from the Eclipse Foundation. Eclipse Californium versions 2.0.0 to 2.7.2, and 3.0.0 to 3.5.0 have security vulnerabilities due to the vulnerability of the DTLS stack to denial of service attacks
