CVE-2024-56518Network attack vector

Unauthenticated code execution via JNDI configuration upload

Published Apr 17, 2025 · Updated Apr 22, 2025

Code injection in Hazelcast Management Center through 6.0 allows remote attackers to execute arbitrary code via a client configuration upload. The /cluster-connections endpoint accepts a hazelcast-client XML document whose JndiLoginModule user.provider.url triggers JNDI loading of attacker-selected content. No credentials or user interaction are required, and successful execution runs with the Management Center process privileges.
