What is CVE-2022-29170?
CVE-2022-29170 is a medium-severity server-side request forgery vulnerability in Grafana Grafana, published on 20 May 2022. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
Grafana is an open-source platform for monitoring and observability. In Grafana Enterprise, the Request security feature allows list allows to configure Grafana in a way so that the instance doesn’t call or only calls specific hosts. The vulnerability present starting with version 7.4.0-beta1 and prior to versions 7.5.16 and 8.5.3 allows someone to bypass these security configurations if a malicious datasource (running on an allowed host) returns an HTTP redirect to a forbidden host. The vulnerability only impacts Grafana Enterprise when the Request security allow list is used and there is a possibility to add a custom datasource to Grafana which returns HTTP redirects. In this scenario, Grafana would blindly follow the redirects and potentially give secure information to the clients. Grafana Cloud is not impacted by this vulnerability. Versions 7.5.16 and 8.5.3 contain a patch for this issue. There are currently no known workarounds.
