CVE-2021-39226 – Grafana Authentication Bypass Vulnerability

https://notcve.org/view.php?id=CVE-2021-39226

Grafana is an open source data visualization platform. In affected versions unauthenticated and authenticated users are able to view the snapshot with the lowest database key by accessing the literal paths: /dashboard/snapshot/:key, or /api/snapshots/:key. If the snapshot "public_mode" configuration setting is set to true (vs default of false), unauthenticated users are able to delete the snapshot with the lowest database key by accessing the literal path: /api/snapshots-delete/:deleteKey. Regardless of the snapshot "public_mode" setting, authenticated users are able to delete the snapshot with the lowest database key by accessing the literal paths: /api/snapshots/:key, or /api/snapshots-delete/:deleteKey. The combination of deletion and viewing enables a complete walk through all snapshot data while resulting in complete snapshot data loss. • http://www.openwall.com/lists/oss-security/2021/10/05/4 https://github.com/grafana/grafana/commit/2d456a6375855364d098ede379438bf7f0667269 https://github.com/grafana/grafana/security/advisories/GHSA-69j6-29vr-p3j9 https://grafana.com/docs/grafana/latest/release-notes/release-notes-7-5-11 https://grafana.com/docs/grafana/latest/release-notes/release-notes-8-1-6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DCKBFUSY6V4VU5AQUYWKISREZX5NLQJT https://lists.fedoraproject • CWE-287: Improper Authentication CWE-639: Authorization Bypass Through User-Controlled Key •
