Python Ethical Hacking - VULNERABILITY SCANNER(2)

VULNERABILITY_SCANNER

How to discover a vulnerability in a web application?

1. Go into every possible page.

2. Look for ways to send data to web application(URL + Forms).

3. Send payloads to discover vulnerabilities.

4. Analyze the response to check of the website is vulnerable.

->General steps are the same regardless of the vulnerability.

Class Scanner.

#!/usr/bin/env python

import requests
import re
from urllib.parse import urljoin


class Scanner:
    def __init__(self, url):
        self.target_url = url
        self.target_links = []

    def extract_links_from(self, url):
        response = requests.get(url)
        return re.findall('(?:href=")(.*?")', response.content.decode())

    def crawl(self, url):
        href_links = self.extract_links_from(url)
        for link in href_links:
            link = urljoin(url, link)

            if "#" in link:
                link = link.split("#")[0]

            if self.target_url in link and link not in self.target_links:
                self.target_links.append(link)
                print(link)
                self.crawl(link)

Vulnerability scanner.

#!/usr/bin/env python

import scanner

target_url = "http://10.0.0.45/mutillidae/"
vuln_scanner = scanner.Scanner(target_url)
vuln_scanner.crawl(target_url)

The Python program runs fine.

Polish the Python code using Default Parameters.

Class Scanner.

#!/usr/bin/env python

import requests
import re
from urllib.parse import urljoin


class Scanner:
    def __init__(self, url):
        self.target_url = url
        self.target_links = []

    def extract_links_from(self, url):
        response = requests.get(url)
        return re.findall('(?:href=")(.*?")', response.content.decode())

    def crawl(self, url=None):
        if url == None:
            url = self.target_url
        href_links = self.extract_links_from(url)
        for link in href_links:
            link = urljoin(url, link)

            if "#" in link:
                link = link.split("#")[0]

            if self.target_url in link and link not in self.target_links:
                self.target_links.append(link)
                print(link)
                self.crawl(link)

Vuln_scanner:

#!/usr/bin/env python

import scanner

target_url = "http://10.0.0.45/mutillidae/"
vuln_scanner = scanner.Scanner(target_url)
vuln_scanner.crawl()
