{"cve":"CVE-2024-37309","nvd":{"published":"2024-06-13T14:15:13.060","modified":"2026-06-17T07:38:06.980","status":"Analyzed","description":"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`. This vulnerability allows an attacker to perform a denial of service attack by exhausting server CPU resources through repeated TLS renegotiations. This impacts the availability of services running on the affected server, posing a significant risk to operational stability and security. TLS 1.3 explicitly forbids renegotiation, since it closes a window of opportunity for an attack. Version 5.7.2 of CrateDB contains the fix for the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-770"],"references":["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","https://cratedb.com/docs/crate/reference/en/latest/appendices/release-notes/5.7.2.html","https://github.com/crate/crate/commit/1dde03bdf031a20886065195527e368e4a3218b3"],"products":["cratedb:cratedb"],"source":"nvd","synced_at":"2026-10-19T21:51:20.603330631+00:00"},"epss":{"cve":"CVE-2024-37309","score":0.00704,"percentile":0.5334,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-x268-qpg6-w9g2","url":"https://osv.dev/vulnerability/GHSA-x268-qpg6-w9g2","summary":"CrateDB has a Client initialized Session-Renegotiation DoS","modified":"2026-09-10T03:50:16.029525629Z","packages":[{"ecosystem":"Maven","name":"io.crate:crate","purl":"pkg:maven/io.crate/crate","ranges":["<5.7.2"],"fixed":["5.7.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
