WID-SEC-W-2023-1536
Vulnerability from csaf_certbund - Published: 2023-06-21 22:00 - Updated: 2023-06-21 22:00Es existiert eine Schwachstelle in Kubernetes. Der Fehler besteht in kOps, wenn der GCP-Provider im Gossip-Modus ausgeführt wird. Ein Angreifer aus dem angrenzenden Netzwerk kann diese Schwachstelle ausnutzen, indem er einen im Cluster ausgeführten Container verwendet, um vertrauliche Informationen aus dem State Storage Bucket abzurufen und sein Rechte zu Cluster-Admin-Berechtigungen zu eskalieren.
