How to Fix CVE-2022-21703

To remediate this vulnerability, upgrade all affected Github.com/grafana/grafana/pkg/web 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/pkg/web fixed: 7.5.15
Upgrade github.com/grafana/grafana/pkg/web to 7.5.15
github.com/grafana/grafana/pkg/web fixed: 8.3.5
Upgrade github.com/grafana/grafana/pkg/web to 8.3.5
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/pkg/web

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-21703, inspect your project dependencies for Github.com/grafana/grafana/pkg/web:

inspect dependencies for github.com/grafana/grafana/pkg/web

Analyze the terminal output to locate any version of Github.com/grafana/grafana/pkg/web in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.5.15), 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-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Github.com/grafana/grafana/pkg/web, 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 8.3.5 and 7.5.15. This patch release includes MEDIUM severity security fix for Cross Site Request Forgery for Grafana. Release v.8.3.5, only containing security fixes: - [Download Grafana 8.3.5](https://grafana.com/grafana/download/8.3.5) - [Release notes](https://grafana.com/docs/grafana/latest/release-notes/release-notes-8-3-5/) Release v.7.5.15, only containing security fixes: - [Download Grafana 7.5.15](https://grafana.com/grafana/download/7.5.15) - [Release notes](https://grafana.com/docs/grafana/latest/release-notes/release-notes-7-5-15/) ## CSRF ([CVE-2022-21703](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-21703)) ### Summary On Jan. 18, security researchers [jub0bs](https://twitter.com/jub0bs) and [abrahack](https://twitter.com/theabrahack) contacted Grafana to disclose a CSRF vulnerability which allows anonymous attackers to elevate their privileges by mounting cross-origin attacks against authenticated high-privilege Grafana users (for example, Editors or Admins). We believe that this vulnerability is rated at CVSS 6.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:N/A:N). ### Impact An attacker can exploit this vulnerability for privilege escalation by tricking an authenticated user into inviting the attacker as a new user with high privileges. ### Affected versions with MEDIUM severity All Grafana >=3.0-beta1 versions are affected by this vulnerability. ### Solutions and mitigations All installations after Grafana v3.0-beta1 should be upgraded as soon as possible. Note that if you are running Grafana behind any reverse proxy, you need to make sure that you are passing the original Host and Origin headers from the client request to Grafana. In the case of Apache Server, you need to add `ProxyPreserveHost on` in your proxy [configuration](https://httpd.apache.org/docs/2.4/mod/mod_proxy.html). In case of NGINX, you can need to add `proxy_set_header Host $http_host;` in your [configuration](http://nginx.org/en/docs/http/ngx_http_proxy_module.html). 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. ### Timeline and postmortem Here is a detailed timeline starting from when we originally learned of the issue.
