CVE-2023-54355 · PocketMine-MP 5.2.0 Server Crash via Incorrect EC Curve

This page contains facts from public vulnerability sources. Check the original advisory before updating.

PocketMine-MP versions before 5.3.1 and 4.23.1 fail to validate that the identityPublicKey in LoginPacket uses the required secp384r1 elliptic curve. Attackers can provide LoginPackets with keys using different curves or non-EC key types to pass login verification but trigger an uncaught exception during ECDH key derivation, crashing the server.
