{"schemaVersion":3,"id":"CVE-2025-49012","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Himmelblau is an interoperability suite for Microsoft Azure Entra ID and Intune. Himmelblau versions 0.9.0 through 0.9.14 and 1.00-alpha are vulnerable to a privilege escalation issue when Entra ID group-based access restrictions are configured using group display names instead of object IDs. Starting in version 0.9.0, Himmelblau introduced support for specifying group names in the `pam_allow_groups` configuration option. However, Microsoft Entra ID permits the creation of multiple groups with the same `displayName` via the Microsoft Graph API—even by non-admin users, depending on tenant settings. As a result, a user could create a personal group with the same name as a legitimate access group (e.g., `\"Allow-Linux-Login\"`), add themselves to it, and be granted authentication or `sudo` rights by Himmelblau. Because affected Himmelblau versions compare group names by either `displayName` or by the immutable `objectId`, this allows bypassing access control mechanisms intended to restrict login to members of official, centrally-managed groups. This issue is fixed in Himmelblau version **0.9.15** and later. In these versions, group name matching in `pam_allow_groups` has been deprecated and removed, and only group `objectId`s (GUIDs) may be specified for secure group-based filtering. To mitigate the issue without upgrading, replace all entries in `pam_allow_groups` with the objectId of the target Entra ID group(s) and/or audit your tenant for groups with duplicate display names using the Microsoft Graph API.","dates":{"published":"2025-06-05T22:29:40.744Z","modified":"2025-06-09T14:47:19.431Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.4,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5.4,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5.4,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00345,"percentile":0.26786,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00345},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00345,"percentile":0.26786}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00345,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score"
