{"cve":"CVE-2023-46740","nvd":{"published":"2024-01-03T17:15:10.590","modified":"2026-06-17T06:31:27.693","status":"Modified","description":"CubeFS is an open-source cloud-native file storage system. Prior to version 3.3.1, CubeFS used an insecure random string generator to generate user-specific, sensitive keys used to authenticate users in a CubeFS deployment. This could allow an attacker to predict and/or guess the generated string and impersonate a user thereby obtaining higher privileges. When CubeFS creates new users, it creates a piece of sensitive information for the user called the “accessKey”. To create the \"accesKey\", CubeFS uses an insecure string generator which makes it easy to guess and thereby impersonate the created user. An attacker could leverage the predictable random string generator and guess a users access key and impersonate the user to obtain higher privileges. The issue has been fixed in v3.3.1. There is no other mitigation than to upgrade.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-330"],"references":["https://github.com/cubefs/cubefs/commit/8555c6402794cabdf2cc025c8bea1576122c07ba","https://github.com/cubefs/cubefs/security/advisories/GHSA-4248-p65p-hcrm","https://github.com/cubefs/cubefs/commit/8555c6402794cabdf2cc025c8bea1576122c07ba","https://github.com/cubefs/cubefs/security/advisories/GHSA-4248-p65p-hcrm"],"products":["linuxfoundation:cubefs"],"source":"nvd","synced_at":"2026-10-19T21:43:38.875533635+00:00"},"epss":{"cve":"CVE-2023-46740","score":0.00439,"percentile":0.38209,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-4248-p65p-hcrm","url":"https://osv.dev/vulnerability/GHSA-4248-p65p-hcrm","summary":"Insecure random string generator used for sensitive data","modified":"2026-09-10T03:50:04.702917631Z","packages":[{"ecosystem":"Go","name":"github.com/cubefs/cubefs","purl":"pkg:golang/github.com/cubefs/cubefs","ranges":["<3.3.1"],"fixed":["3.3.1"]}]},{"id":"GO-2024-2431","url":"https://osv.dev/vulnerability/GO-2024-2431","summary":"Insecure random string generator used for sensitive data in github.com/cubefs/cubefs","modified":"2024-07-09T19:33:56Z","packages":[{"ecosystem":"Go","name":"github.com/cubefs/cubefs","purl":"pkg:golang/github.com/cubefs/cubefs","ranges":["all versions"],"fixed":[]}]}],"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).
