{"id":"GHSA-vcmv-6rxx-fh7r","summary":"OpenStack Nova Exposure of Sensitive Information to an Unauthorized Actor","details":"OpenStack Nova before 2012.1 allows someone with access to an EC2_ACCESS_KEY (equivalent to a username) to obtain the EC2_SECRET_KEY (equivalent to a password). Exposing the EC2_ACCESS_KEY via http or tools that allow man-in-the-middle over https could allow an attacker to easily obtain the EC2_SECRET_KEY. An attacker could also presumably brute force values for EC2_ACCESS_KEY.","aliases":["CVE-2011-4076","PYSEC-2026-691"],"modified":"2026-07-06T08:11:25.842143637Z","published":"2022-04-22T00:24:18Z","database_specific":{"github_reviewed_at":"2024-05-08T19:51:54Z","nvd_published_at":"2019-11-26T04:15:00Z","cwe_ids":["CWE-200"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2011-4076"},{"type":"WEB","url":"https://github.com/openstack/nova/commit/b1ab6da1495784ff581000018a6047fd19cf82c4"},{"type":"WEB","url":"https://github.com/openstack/nova/commit/beee11edbfdd82cd81bc9c0fd75912c167892c2b"},{"type":"WEB","url":"https://access.redhat.com/security/cve/cve-2011-4076"},{"type":"WEB","url":"https://bugs.launchpad.net/nova/+bug/868360"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2011-4076"},{"type":"WEB","url":"https://security-tracker.debian.org/tracker/CVE-2011-4076"},{"type":"WEB","url":"https://www.openwall.com/lists/oss-security/2011/10/25/4"}],"affected":[{"package":{"name":"nova","ecosystem":"PyPI","purl":"pkg:pypi/nova"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"12.0.0a0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/04/GHSA-vcmv-6rxx-fh7r/GHSA-vcmv-6rxx-fh7r.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
