CVE-2020-15378

Container service exposure via unrestricted IPv6 networking

Published Jun 9, 2021 · Updated Aug 4, 2024

Network exposure in Brocade SANnav before 2.1.1 allows attackers to reach Docker container ports through IPv6 networking. IPv6 configuration during OVA installation or through change-ipv4-installation-to-ipv6.sh leaves numerous Docker container ports exposed. The affected state requires an OVA deployment with IPv6 enabled, and the documented impact is limited to exposure of listening services.
