CVE-2024-37309Public exploitNetwork attack vector

Service interruption via client-initiated TLS renegotiation

Published Jun 13, 2024 · Updated Aug 2, 2024

TLS renegotiation in CrateDB before 5.7.2 allows remote attackers to interrupt service through repeated requests on port 4200. The TLS 1.2 endpoint accepts client-initiated renegotiation during an established session, repeatedly performing CPU-intensive security handshakes. Network access to a TLS-enabled cluster is sufficient; sustained renegotiation requests exhaust server CPU and overload the database service.
