Description Anten Skrabec 2021-06-03 18:20:37 UTC 
The NetworkPolicy resources installed for Maistra do not properly specify which ports may be accessed. This allows access to all ports on these resources from any pod.

For example, the ports for istiod are currently specified as:

spec: 
  ingress: 
  - ports: 
    port: webhook

and should be specified as:

spec: 
  ingress: 
    ports: 
    - port: webhook
 

Network policies applied to the following resources are affected:
- istiod
- grafana
- kiali
- prometheus
- jaeger
- galley
- sidecar injector
