What it is about
Grafana ist eine Analyse- und Visualisierungssoftware. Ein entfernter, anonymer oder authentisierter Angreifer kann mehrere Schwachstellen in Grafana ausnutzen, um einen Denial of Service Angriff durchzuführen oder sich erhöhte Berechtigungen zu verschaffen.
Under what conditions?
Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.
What can happen in the worst case
An attacker could use the vulnerability to
- einen Denial of Service Angriff durchzuführen oder sich erhöhte Berechtigungen zu verschaffen
