Detailsinfo

A vulnerability, which was classified as very critical, has been found in D2iQ DC OS Marathon up to 1.8.x. Affected by this issue is an unknown part of the component Docker Container Handler. The manipulation with an unknown input leads to a permission assignment vulnerability. Using CWE to declare the problem leads to CWE-732. The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The Marathon UI in DC/OS < 1.9.0 allows unauthenticated users to deploy arbitrary Docker containers. Due to improper restriction of volume mount configurations, attackers can deploy a container that mounts the host's root filesystem (/) with read/write privileges. When using a malicious Docker image, the attacker can write to /etc/cron.d/ on the host, achieving arbitrary code execution with root privileges. This impacts any system where the Docker daemon honors Marathon container configurations without policy enforcement.
