Hello !

Here's the commands I used that triggered the error

python3 /KubiScan/KubiScan.py -ho $KUBERNETES_ENDPOINT:$PORT -t /token -c /ca.crt -rp
or
python3 /KubiScan/KubiScan.py -ho $KUBERNETES_ENDPOINT:$PORT -t /token -c /ca.crt -pp

 Traceback (most recent call last):
   File "/KubiScan/KubiScan.py", line 635, in <module>
     main()
   File "/KubiScan/KubiScan.py", line 568, in main

     risky_containers = get_risky_containers(pod, risky_users, deep_analysis)
   File "/KubiScan/engine/utils.py", line 331, in get_risky_containers
     for volume in pod.spec.volumes:
 TypeError: 'NoneType' object is not iterable

Not sure if this happen with the other commands because when I run them they actually returning a result.

Cheers !

Hey @JnMik,
Thank you for reporting !

I will check it and update you when it will be solved.
I think I know what will solve it but it will need to wait for after 4.12 because I am presenting demos of this tool and I don't want to add fixes that might affect the demos.

Sorry for the delay,

I saw that the problem is in this here:

KubiScan/engine/utils.py

Line 333 in c20370a

for volume in pod.spec.volumes:

This is because we are not handling the case where pod.spec.volumes is None.
I was able to reproduce it with this YAML:

apiVersion: v1
kind: Pod
metadata:
  name: super-user-pod
spec:
  containers:
  - image: busybox:1.28
    imagePullPolicy: IfNotPresent
    name: redis
    resources: {}
    securityContext:
      capabilities:
        add:
        - SYS_ADMIN
  dnsPolicy: ClusterFirst
  enableServiceLinks: true
  restartPolicy: Always
  automountServiceAccountToken: false

I can now work on solution for this and I will update.

I tested it and it works :)
If you still having issues, reopen this case.
