CyberRota Analysis

AI-Generated

The vulnerability affects the Amazon EFS CSI Driver in Kubernetes, allowing authenticated users with PersistentVolume creation privileges to exploit a flaw in the volume deletion component. This could lead to unauthorized recursive deletion of directories on an EFS filesystem by manipulating the volumeHandle to link access points across different filesystems. Organizations using Kubernetes with the affected driver should prioritize upgrading to version v3.4.1 to mitigate this high-severity risk.

Original NVD Description

Unverified ownership of a storage access point in the volume deletion component of the Amazon EFS CSI Driver before v3.4.1 might allow an authenticated Kubernetes user with PersistentVolume creation privileges to cause recursive deletion of directories on an EFS filesystem they are not authorized to access, via a crafted PersistentVolume volumeHandle that pairs an access point from one filesystem with a different target filesystem. To remediate this issue, users should upgrade to version v3.4.1.
