CVE-2024-37309 – Client initialized Session-Renegotiation DoS

https://notcve.org/view.php?id=CVE-2024-37309

CrateDB is a distributed SQL database. A high-risk vulnerability has been identified in versions prior to 5.7.2 where the TLS endpoint (port 4200) permits client-initiated renegotiation. In this scenario, an attacker can exploit this feature to repeatedly request renegotiation of security parameters during an ongoing TLS session. This flaw could lead to excessive consumption of CPU resources, resulting in potential server overload and service disruption. The vulnerability was confirmed using an openssl client where the command `R` initiates renegotiation, followed by the server confirming with `RENEGOTIATING`. • https://cratedb.com/docs/crate/reference/en/latest/appendices/release-notes/5.7.2.html https://github.com/crate/crate/commit/1dde03bdf031a20886065195527e368e4a3218b3 https://github.com/crate/crate/security/advisories/GHSA-x268-qpg6-w9g2 • CWE-770: Allocation of Resources Without Limits or Throttling •
