# CVE-2022-2576

## Summary

- **CVE ID:** CVE-2022-2576
- **Severity:** UNKNOWN
- **CVSS Score:** 0.01
- **CWE:** CWE-408
- **Published:** Jul 29, 2022
- **Last Modified:** Mar 13, 2026

## Description

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.

## Affected Products

- The Eclipse Foundation — Eclipse Californium (2.0.0)
- The Eclipse Foundation — Eclipse Californium (unspecified)
- The Eclipse Foundation — Eclipse Californium (3.0.0)
