Eclipse Californium denial of service (DoS) via Datagram Transport Layer Security (DTLS) handshake on parameter mismatch
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | org.eclipse.californium:californium-core | >= 2.0.0, < 2.7.3 | 2.7.3 |
| Maven | org.eclipse.californium:californium-core | >= 3.0.0, < 3.6.0 | 3.6.0 |
Details
As written in the advisory (Markdown source, shown as plain text).
In Eclipse Californium versions 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.
