Name of the Vulnerable Software and Affected Versions
Kube-proxy versions (affected versions not specified)
Description
The issue concerns Kube-proxy on Windows, which can unintentionally forward traffic to local processes listening on the same port (
spec.ports[*].port) as a LoadBalancer Service. This occurs when the LoadBalancer controller does not set the status.loadBalancer.ingress[].ip field. Clusters where the LoadBalancer controller sets this field are unaffected.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
