It ships the binary hawk_invoke (built from tools/hawk_invoke.c), intended to be used as a setuid program. This allows the hacluster user to invoke certain commands as root (with an attempt to limit this to safe combinations). This user is able to execute an interactive \"shell\" that isn't limited to the commands specified in hawk_invoke, allowing escalation to root.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-269"],"references":["https://bugzilla.suse.com/show_bug.cgi?id=1180571","https://github.com/ClusterLabs/crmsh/commit/c538024b8ebd138dc373b005189471d9b77e9c82","https://github.com/ClusterLabs/hawk/releases","https://bugzilla.suse.com/show_bug.cgi?id=1180571","https://github.com/ClusterLabs/crmsh/commit/c538024b8ebd138dc373b005189471d9b77e9c82"],"products":["clusterlabs:hawk"],"source":"nvd","synced_at":"2026-10-19T21:35:14.992143698+00:00"},"epss":{"cve":"CVE-2021-3020","score":0.01254,"percentile":0.69473,"date":"2026-10-31"},"kev":null,"osv":[],"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).
