Libvirtd is deployed by default (by director) listening on 0.0.0.0 (all interfaces) with no-authentication or encryption. Anyone able to make a TCP connection to any compute host IP address, including 127.0.0.1, other loopback interface addresses, or in some cases possibly addresses that have been exposed beyond the management interface, could use this to open a virsh session to the libvirtd instance and gain control of virtual machine instances or possibly take over the host.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":10.0},"cwes":["CWE-306"],"references":["http://www.securityfocus.com/bid/98576","https://access.redhat.com/errata/RHSA-2017:1242","https://access.redhat.com/errata/RHSA-2017:1504","https://access.redhat.com/errata/RHSA-2017:1537","https://access.redhat.com/errata/RHSA-2017:1546"],"products":["redhat:openstack"],"source":"nvd","synced_at":"2026-10-19T20:52:03.425131697+00:00"},"epss":{"cve":"CVE-2017-2637","score":0.04604,"percentile":0.9167,"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).
