Description Agostino Sarubbo gentoo-dev 2020-06-03 14:24:23 UTC
From :

Dear all,

today we are releasing Grafana 6.7.4 and 7.0.2. These patch releases
include an important security fix for an issue that affects all
Grafana versions from 3.0.1 to 7.0.1.

Incorrect access control vulnerability (CVE-2020-13379)
We received a security report to on May 14, 2020,
about a vulnerability in Grafana regarding the avatar feature. It was
later identified as affecting Grafana versions from 3.0.1 to 7.0.1.
CVE-2020-13379 has been assigned to this vulnerability.

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.

If for some reason you cannot upgrade, the impact can be mitigated by
blocking access to the avatar feature by blocking the /avatar/* URL
via a web application firewall, load balancer, reverse proxy, or
similar. It can also be mitigated by restricting access to Grafana.

Affected versions
Grafana releases 3.0.1 through 7.0.1

Patched versions
7.x and 6.7.x

Solutions and mitigations
Download and install the appropriate patch for your version of Grafana.

Grafana Cloud instances have already been patched, and Grafana
Enterprise customers were provided with updated binaries, under
embargo, on May 27.

Last vulnerable version appears to have been removed in the rename to 6.7.4. No stable versions, no GLSA, closing.
