Alternatively if you're on AWS, EgressNetworkPolicy is not supported, you can use a Static IP, [2], for projects to force projects which need storage to connect from a NIC with a unique IP Address. \nOnce traffic is coming from a known IP address, not the Node IP, you can protect the NFS, or GlusterFS storage node with a firewall, or exports which only allows access from the Egress router, or from the Static IP. \nAn egress policy such as the one in the redirect-mode, [3], is an example of egress policy which would mitigate this vulnerability. An administrator would need to deploy one of these to the project using storage, as they need to run in privileged mode. This forces all traffic to the storage device through the egress router, which is a distinct IP. You can then configure the storage device to only access traffic from that source IP.\nBe aware that during a docker build, the build container is not subject to EgressNetworkPolicy rules in versions prior to 3.7. Also the Static IP feature is only available as a Tech Preview from version 3.7.\nAn alternative mitigation if you're using Red Hat Gluster Storage is outlined here: https://github.com/gluster/gluster-kubernetes/blob/master/docs/design/tls-security.md\nA semi-automatic namespace wide egress-IP is due to be released in OCP 3.11 which will make management of the EgressNetworkPolicy easier. It will only work for the multitenant and networkpolicy plugins.\n[1] https://docs.openshift.com/container-platform/3.7/admin_guide/managing_networking.html#admin-guide-controlling-egress-traffic\n[2] https://docs.openshift.com/container-platform/3.7/admin_guide/managing_networking.html#enabling-static-ips-for-external-project-traffic\n[3] https://docs.openshift.org/latest/admin_guide/managing_networking.html#admin-guide-deploying-an-egress-router-pod"}, "name": "CVE-2018-1069", "package_state": [{"cpe": "cpe:/a:redhat:openshift:3", "fix_state": "Will not fix", "package_name": "Networking", "product_name": "Red Hat OpenShift Enterprise 3"}], "public_date": "2018-03-08T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2018-1069\nhttps://nvd.nist.gov/vuln/detail/CVE-2018-1069"], "threat_severity": "Important"}
