Privilege escalation (CVE-2022-35957)

Summary

On August 9 an internal security review identified a vulnerability in the Grafana which allows an escalation from Admin privileges to Server Admin when Auth proxy authentication is used.

Auth proxy allows to authenticate a user by only providing the username (or email) in a X-WEBAUTH-USER HTTP header: the trust assumption is that a front proxy will take care of authentication and that Grafana server is publicly reachable only with this front proxy.

Datasource proxy breaks this assumption:

  • it is possible to configure a fake datasource pointing to a localhost Grafana install with a X-WEBAUTH-USER HTTP header containing admin username.
  • This fake datasource can be called publicly via this proxying feature.

The CVSS score for this vulnerability is 6.6 Moderate (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H).

Impacted versions

All Grafana installations where the Auth Proxy is used.

Solutions and mitigations

To fully address CVE-2022-35957 please upgrade your Grafana instances. They are only required if you are using Auth proxy. If you can’t upgrade, as an alternative, you can deactivate the auth proxy.

Appropriate patches have been applied to Grafana Cloud.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/grafana/grafana, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/grafana/grafana to 9.1.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-35957 is resolved across your whole dependency graph.

  3. Workarounds

    Close the privilege gap rather than the entry point: audit which accounts, roles and service identities can reach the affected operation, drop the component to the least privilege it actually needs, and review file and directory permissions created by earlier installs — a default left in place is what makes this reachable.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
