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.

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. En el sistema de alertas de Grafana, los usuarios con permisos de edición para un punto de contacto, específicamente los permisos 'alert.notifications:write' o 'alert.notifications.receivers:test' que se otorgan como parte del rol fijo 'Contact Point Writer', que forma parte del rol básico Editor - pueden editar puntos de contacto creados por otros usuarios, modificar la URL del endpoint a un servidor controlado. Al invocar la funcionalidad de prueba, los atacantes pueden capturar y extraer configuraciones seguras redactadas, como credenciales de autenticación para servicios de terceros (p. ej., tokens de Slack).
