Google Cloud addressed a medium-severity security flaw that could allow escalation of privileges for attackers with access to a Kubernetes cluster. Palo Alto Networks Unit 42 discovered the vulnerability, which could lead to data theft and disruption of cluster operations. The issue has been fixed in specific versions of Google Kubernetes Engine and Anthos Service Mesh.
Key Meeting Takeaways:
– Google Cloud has recently addressed a medium-severity security flaw in its platform related to a vulnerability in Fluent Bit logging container and Anthos Service Mesh (ASM).
– The flaw, discovered by Palo Alto Networks Unit 42, could allow an attacker who has compromised a Fluent Bit container to escalate their privileges in a Kubernetes cluster with ASM enabled.
– The issue has been addressed in specific versions of Google Kubernetes Engine (GKE) and Anthos Service Mesh (ASM).
– Google has removed Fluent Bit’s access to service account tokens and re-architected ASM functionality to remove excessive role-based access control (RBAC) permissions to mitigate the risk.
– Cloud vendors automatically create system pods with elevated privileges when clusters are launched, presenting security risks.
