How to Fix CVE-2020-13379

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: 6.7.4 
Upgrade github.com/grafana/grafana to 6.7.4
github.com/grafana/grafana fixed: 7.0.2 
Upgrade github.com/grafana/grafana to 7.0.2
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-2020-13379, 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 6.7.4), 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-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. 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

The avatar feature in Grafana (github.com/grafana/grafana/pkg/api/avatar) 3.0.1 through 7.0.1 has an SSRF Incorrect Access Control issue that allows remote code execution. This vulnerability allows any unauthenticated user/client to make Grafana send HTTP requests to any URL and return its result to the user/client. This can be used to gain information about the network that Grafana is running on.
