CVE-2017-1002101

Description

It was found that volume security can be sidestepped with innocent emptyDir and subpath. This could give an attacker with access to a pod full control over the node host by gaining access to docker socket.

Statement

This flaw allows a pod to mount any part of the host filesystem. The pod will run with the security contraints placed on the user but could read anything with o=rx mode and appropriate SELinux label.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
