Attack-Flow Graph

Executive Summary

This vulnerability is an improper neutralization of argument delimiters in the volume handling component of the AWS EFS CSI Driver before version 3.0.1. It allows remote authenticated users who have permissions to create PersistentVolumes to inject arbitrary mount options by exploiting comma injection.

Impact Analysis

The vulnerability can impact you by allowing an authenticated user with PersistentVolume creation permissions to inject arbitrary mount options. This could lead to unauthorized changes in how volumes are mounted, potentially compromising the confidentiality and integrity of data accessed through these volumes.

Mitigation Strategies

To remediate this issue, users should upgrade the AWS EFS CSI Driver to version v3.0.1 or later.
