Описание
In Grafana's alerting system, users with edit permissions for a contact point, specifically the permissions “alert.notifications:write” or “alert.notifications.receivers:test” that are granted as part of the fixed role "Contact Point Writer", which is part of the basic role Editor - can edit contact points created by other users, modify the endpoint URL to a controlled server. By invoking the test functionality, attackers can capture and extract redacted secure settings, such as authentication credentials for third-party services (e.g., Slack tokens). This leads to unauthorized access and potential compromise of external integrations.
A flaw was found in Grafana's alerting system. Users with editor permissions, specifically those able to write or test alert notifications, can modify contact points created by other users. By changing the endpoint URL to a controlled server and triggering the test functionality, an attacker can capture and extract sensitive secure settings, such as authentication credentials for third-party services. This vulnerability leads to unauthorized access and potential compromise of external integrations.
Отчет
This vulnerability has a Low impact on Red Hat products. The flaw in Grafana's alerting system allows an authenticated user with "Contact Point Writer" permissions (part of the Editor role) to disclose secure settings. Exploitation requires the attacker to modify an existing contact point and test it against a controlled external server.
Меры по смягчению последствий
To mitigate this issue, administrators should review and restrict user permissions within Grafana. Ensure that only trusted users are granted the "Contact Point Writer" role or any role that includes "alert.notifications:write" or "alert.notifications.receivers:test" permissions. Limiting the number of users with such elevated privileges reduces the attack surface. If the Grafana service is reconfigured, a restart may be required for changes to take effect.
