Summary

Amazon EFS CSI Driver before v3.4.1 has a vulnerability in the volume deletion component where unverified ownership of a storage access point 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.

Risk Assessment

A user can unauthorizedly delete data on an EFS filesystem, potentially leading to data loss or integrity compromise.

Recommendation

Upgrade the driver to version v3.4.1 or later, which contains the fix.

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.
