[~] The config file is expected to be at "/root/.rustscan.toml"

|
|
[!] File limit is lower than default batch size. Consider upping with --ulimit. May cause harm to sensitive servers
|
||
|
|
[!] Your file limit is very small, which negatively impacts RustScan's speed. Use the Docker image, or up the Ulimit with '--ulimit 5000'.

At the bottom we can see the version of `Monitor` which is front end to display status of any web applicaiton.
|
||
|

|
|
We can see that path where it uploads our reverse shell
|
||
|
|
|
||
|
|
<img src="https://imgur.com/JV7wrFq.png"/>
|
||
|
|
|
||
|
|
Run the exploit
|
||
|
|
|
||
|
|
<img src="https://imgur.com/rZ8nl1T.png"/>
|
||
|
|
|
||
|
|
And setup a netcat listner also to visit where the reverse shell is uploaded
|
||
|
|
|
||

|
||
|
|
|
||
|
|
We can see a note
|
||
|
|
|
||
|

|

|
|
Now running `sudo -l` we can see that we can `hping3` but with --icmp
|
||
|
|
|
||
|
|
<img src="https://imgur.com/1AjAh8B.png"/>
|
||
|
|
|
||
|
|
So run hping3 with icmp on localhost and send `id_rsa` and receive on localhost
