Grafana is an open-source platform for monitoring and observability.

In Grafana Enterprise, Request security is a deny list that allows admins to configure Grafana in a way so that the instance doesn’t call specific hosts.

However, the restriction can be bypassed used punycode encoding of the characters in the request address.

CVE-2023-2801 Grafana data source proxy race condition

If you send an API call to the /ds/query or public dashboard query endpoint (if public dashboards is enabled) that has mixed queries (i.e. 2 or more distinct data sources in one API call), you can crash your Grafana instance. The only feature that uses mixed queries within Grafana right now is public dashboards, but it is also possible to cause this by calling the API directly. Steps to reproduce If public dashboards are enabled, just hit a public dashboard under heavy load. If public dashboards is disabled, the only way you can reproduce this is by hitting the /ds/query endpoint with a mixed query payload under heavy load with a load testing script.

CVE-2023-2183 Broken access control test alerts

The application allows an attacker in the Viewer role, send alerts by API Alert - Test. The option is not available from the user panel UI for the Viewer role.

The API does not check access to this function and allows it by users with the least rights, for example, the Viewer that does not see this option in the user panel. This enables malicious users to abuse the functionality by sending multiple alert messages (e-mail, slack, etc…), spamming users, prepare Phishing attack or blocked SMTP server / IP and automatically moved all message to spam folder, add to black list IP.
