    CVE-2025-67499 (GCVE-0-2025-67499)

    Vulnerability from nvd – Published: 2025-12-09 23:13 – Updated: 2025-12-10 16:50
    VLAI
    Title
    CNI Plugins Portmap nftables backend intercepts non-local traffic
    Summary
    The CNI portmap plugin allows containers to emulate opening a host port, forwarding that traffic to the container. Versions 1.6.0 through 1.8.0 inadvertently forward all traffic with the same destination port as the host port when the portmap plugin is configured with the nftables backend, thus ignoring the destination IP. This includes traffic not intended for the node itself, i.e. traffic to containers hosted on the node. Containers that request HostPort forwarding can intercept all traffic destined for that port. This requires that the portmap plugin be explicitly configured to use the nftables backend. This issue is fixed in version 1.9.0. To workaround, configure the portmap plugin to use the iptables backend. It does not have this vulnerability.

    CVE-2020-10749 (GCVE-0-2020-10749)

    Vulnerability from nvd – Published: 2020-06-03 13:45 – Updated: 2024-08-04 11:14
    VLAI
    Summary
    A vulnerability was found in all versions of containernetworking/plugins before version 0.8.6, that allows 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.

    CVE-2025-67499 (GCVE-0-2025-67499)

    Vulnerability from cvelistv5 – Published: 2025-12-09 23:13 – Updated: 2025-12-10 16:50

    Title
    CNI Plugins Portmap nftables backend intercepts non-local traffic
    Summary
    The CNI portmap plugin allows containers to emulate opening a host port, forwarding that traffic to the container. Versions 1.6.0 through 1.8.0 inadvertently forward all traffic with the same destination port as the host port when the portmap plugin is configured with the nftables backend, thus ignoring the destination IP. This includes traffic not intended for the node itself, i.e. traffic to containers hosted on the node. Containers that request HostPort forwarding can intercept all traffic destined for that port. This requires that the portmap plugin be explicitly configured to use the nftables backend. This issue is fixed in version 1.9.0. To workaround, configure the portmap plugin to use the iptables backend. It does not have this vulnerability.

    VLAI
    Summary
    A vulnerability was found in all versions of containernetworking/plugins before version 0.8.6, that allows 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.
