How to Fix CVE-2022-39328

To remediate this vulnerability, upgrade all affected Github.com/grafana/grafana dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/grafana/grafana fixed: 9.2.4
Upgrade github.com/grafana/grafana to 9.2.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for github.com/grafana/grafana

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-39328, inspect your project dependencies for Github.com/grafana/grafana:

inspect dependencies for github.com/grafana/grafana

Analyze the terminal output to locate any version of Github.com/grafana/grafana in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 9.2.4), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'), where the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. In Github.com/grafana/grafana, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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. Appropriate patches have been applied to [Grafana Cloud](https://grafana.com/cloud). ## Reporting security issues If you think you have found a security vulnerability, please send a report to security@grafana.com.
