Description

Grafana is an open-source platform for monitoring and observability. Versions starting with 9.2.0 and less than 9.2.4 contain a race condition in the authentication middlewares logic which may allow an unauthenticated user to query an administration endpoint under heavy load. This issue is patched in 9.2.4. There are no known workarounds.

Understanding This Vulnerability

This Common Vulnerabilities and Exposures (CVE) entry provides detailed information about a security vulnerability that has been publicly disclosed. CVEs are standardized identifiers assigned by MITRE Corporation to track and catalog security vulnerabilities across software and hardware products.

The severity rating (CRITICAL) indicates the potential impact of this vulnerability based on the CVSS (Common Vulnerability Scoring System) framework. Higher severity ratings typically indicate vulnerabilities that could lead to more significant security breaches if exploited. Security teams should prioritize remediation efforts based on severity, exploit availability, and the EPSS (Exploit Prediction Scoring System) score, which predicts the likelihood of exploitation in the wild.

If this vulnerability affects products or systems in your infrastructure, we recommend reviewing the affected products section, checking for available patches or updates from vendors, and implementing recommended workarounds or solutions until a permanent fix is available. Organizations should also monitor security advisories and threat intelligence feeds for updates about active exploitation of this vulnerability.

Advisory Details

Today we are releasing Grafana 9.2.4. Alongside other bug fixes, this patch release includes critical security fixes for CVE-2022-39328. Release 9.2.4, latest patch, also containing security fix: - [Download Grafana 9.2.4](https://grafana.com/grafana/download/9.2.4) Appropriate patches have been applied to [Grafana Cloud](https://grafana.com/cloud) and as always, we closely coordinated with all cloud providers licensed to offer Grafana Pro. They have received early notification under embargo and confirmed that their offerings are secure at the time of this announcement. This is applicable to Amazon Managed Grafana and Azure Managed Grafana as a service offering. ## Privilege escalation ### Summary Internal security audit identified a race condition in the Grafana codebase, which allowed an unauthenticated user to query an arbitrary endpoint in Grafana. A race condition in the [HTTP context creation](https://github.com/grafana/grafana/blob/main/pkg/web/router.go#L153) could make a HTTP request being assigned the authentication/authorization middlewares of another call. Under heavy load it is possible that a call protected by a privileged middleware receives instead the middleware of a public query. As a result, an unauthenticated user can successfully query protected endpoints. The CVSS score for this vulnerability is [9.8 Critical](https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H&version=3.1) ### Impact Unauthenticated users can query arbitrary endpoints with malicious intent. ### Impacted versions All installations for Grafana versions >=9.2.x. ### Solutions and mitigations To fully address CVE-2022-39328, please upgrade your Grafana instances.
