CVE-2020-10749

A vulnerability was found in affected container networking implementations that allow malicious containers in Kubernetes clusters to perform man-in-the-middle (MitM) attacks. A malicious container can exploit this flaw by sending “rogue” IPv6 router advertisements to the host or other containers, to redirect traffic to the malicious container.

Mitigation

Prevent untrusted, non-privileged containers from running with CAP_NET_RAW.
