Vulnerability Title
Snapshot authentication bypass in grafana
来源: 美国国家漏洞数据库 NVD
Vulnerability Description
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. This issue has been resolved in versions 8.1.6 and 7.5.11. If for some reason you cannot upgrade you can use a reverse proxy or similar to block access to the literal paths: /api/snapshots/:key, /api/snapshots-delete/:deleteKey, /dashboard/snapshot/:key, and /api/snapshots/:key. They have no normal function and can be disabled without side effects.

二、漏洞 CVE-2021-39226 的公开POC
#POC 描述源链接神龙链接
1Grafana instances up to 7.5.11 and 8.1.5 allow remote unauthenticated users to view the snapshot associated with the lowest database key by accessing the literal paths /api/snapshot/:key or /dashboard/snapshot/:key. If the snapshot is in public mode, unauthenticated users can delete snapshots by accessing the endpoint /api/snapshots-delete/:deleteKey. Authenticated users can also delete snapshots by accessing the endpoints /api/snapshots-delete/:deleteKey, or sending a delete request to /api/snapshot/:key, regardless of whether or not the snapshot is set to public mode (disabled by default).https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2021/CVE-2021-39226.yamlPOC详情
