CVE-2021-27358
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe snapshot feature in Grafana 6.7.3 through 7.4.1 can allow an unauthenticated remote attackers to trigger a Denial of Service via a remote API call if a commonly used configuration is set.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe snapshot feature in Grafana versions 6.7.3 through 7.4.1 contains a vulnerability that allows unauthenticated remote attackers to trigger a Denial of Service condition via the remote API when a commonly used configuration setting is enabled. The vulnerability stems from insufficient access controls on the snapshot API endpoint.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Grafana versionRun 'grafana-server -v' or check the Grafana admin UI under 'Configuration' > 'Help' to find the installed version numberAffected if The installed version is greater than or equal to 6.7.3 and less than or equal to 7.4.1
-
Identify NetApp E Series Performance AnalyzerCheck if NetApp E Series Performance Analyzer is installed in the environment, as all versions of this product are affectedAffected if NetApp E Series Performance Analyzer is present in the environment
-
Check snapshot anonymous access settingInspect the Grafana configuration file (grafana.ini) or examine the 'Anonymous Access' settings in Grafana under 'Configuration' > 'Server' to see if anonymous access to snapshots is enabledAffected if Anonymous access to snapshots is enabled in the Grafana configuration
-
Check external snapshot publish settingReview the Grafana configuration for 'external_snapshot' or 'snapshot.publish' settings to determine if external snapshot publishing is configuredAffected if External snapshot publishing is enabled or configured in Grafana settings
You are affected if Grafana version 6.7.3 through 7.4.1 is installed with snapshot-related access settings enabled, or if NetApp E Series Performance Analyzer is present in the environment.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade Grafana to version 7.4.2 or later. Additionally, review and restrict the snapshot configuration settings (specifically settings related to external snapshot publishing or anonymous access to snapshots) to limit exposure until the upgrade can be completed.
