{"cve":"CVE-2020-27781","nvd":{"published":"2020-12-18T21:15:12.660","modified":"2026-06-17T03:09:37.927","status":"Modified","description":"User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila, resulting in potential privilege escalation. An Open Stack Manila user can request access to a share to an arbitrary cephx user, including existing users. The access key is retrieved via the interface drivers. Then, all users of the requesting OpenStack project can view the access key. This enables the attacker to target any resource that the user has access to. This can be done to even \"admin\" users, compromising the ceph administrator. This flaw affects Ceph versions prior to 14.2.16, 15.x prior to 15.2.8, and 16.x prior to 16.2.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":7.1},"cwes":["CWE-522"],"references":["https://bugzilla.redhat.com/show_bug.cgi?id=1900109","https://lists.debian.org/debian-lts-announce/2023/10/msg00034.html","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZJ7FFROL25FYRL6FMI33VRKOD74LINRP/","https://security.gentoo.org/glsa/202105-39","https://bugzilla.redhat.com/show_bug.cgi?id=1900109"],"products":["fedoraproject:fedora","redhat:ceph","redhat:ceph_storage","redhat:openshift_container_platform","redhat:openstack_platform"],"source":"nvd","synced_at":"2026-10-19T21:12:09.559580076+00:00"},"epss":{"cve":"CVE-2020-27781","score":0.00295,"percentile":0.22156,"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).
