{"id":"CVE-2017-20198","state":"PUBLISHED","title":"DC/OS Marathon UI < 1.9.0 Unauthenticated RCE via Docker Mount Abuse","description":"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.","publishedAt":"2025-07-23T13:50:52.047Z","updatedAt":"2026-05-15T11:14:26.618Z","severity":{"score":9.3,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["D2iQ, Inc.
