Program Code – Web Vulnerability Scanners in Python: An Analysis

# Importing necessary libraries for web scanning
import requests
from bs4 import BeautifulSoup
import re

# Define a class to encapsulate the web vulnerability scanner
class WebVulnerabilityScanner:
    def __init__(self, url):
        # Initialize the URL and the session
        self.session = requests.Session()
        self.url = url
        self.forms = []

    def extract_forms(self):
        # Get the webpage content
        response = self.session.get(self.url)
        # Parse the webpage using BeautifulSoup
        soup = BeautifulSoup(response.text, 'html.parser')
        # Find all forms in the webpage
        self.forms = soup.find_all('form')
    
    def check_vulnerabilities(self):
        # Check vulnerabilities by attempting to inject code
        for form in self.forms:
            action = form.get('action')
            post_url = self.url + action
            method = form.get('method')
            
            # Create a dictionary for form inputs
            inputs = {}
            for input_tag in form.find_all('input'):
                name = input_tag.get('name')
                input_type = input_tag.get('type', 'text')
                inputs[name] = 'test' if input_type != 'submit' else None

            # Attempt an XSS attack
            inputs = {key: '<script>alert(1)</script>' if value == 'test' else None for key, value in inputs.items()}
            if method.lower() == 'post':
                response = self.session.post(post_url, data=inputs)
            else:
                response = self.session.get(post_url, params=inputs)
            
            # Check if the payload executed
            if '<script>alert(1)</script>' in response.text:
                print(f'Form at {post_url} is vulnerable to XSS.')

# Instantiate the scanner and run the scan
if __name__ == '__main__':
    url = 'http://example.com' # TODO: Replace with the URL you want to scan
    scanner = WebVulnerabilityScanner(url)
    scanner.extract_forms()
    scanner.check_vulnerabilities()

Code Output:

No fixed output. The expected output will depend on the URL being scanned. If a form is vulnerable to XSS, it will print a message indicating the form action’s URL; otherwise, no output will indicate no vulnerabilities found.

Code Explanation:

Let’s untangle this code, piece by piece. Imagine you’re Sherlock Holmes, and this code’s the mystery you gotta solve.

• First off, we import the big guns: requests for sending HTTP requests, BeautifulSoup for parsing HTML, and re for regular expressions (though we didn’t really use ’em here, keeping us on our toes!).
• WebVulnerabilityScanner class is where the magic brews. We’ve got an __init__ method to kick things off with our URL and an empty bowl labeled ‘forms’.
• The extract_forms method is the brainy sidekick, using BeautifulSoup to comb through the webpage’s hair—erm, HTML—and fish out all the forms into our bowl.
• Buckle up! check_vulnerabilities is where the action is. We’re loop-de-looping through each form, cooking up a fake attack to test if the website yelps ‘ouch’ or sits there like a rock.
• For each form, we grab the clean-cut action URL and check how it likes its data served—POST or GET, no discrimination here.
• We fill in all the input fields with <script>alert(1)</script>, a classic XSS attack that pops an alert if the site’s guard is dozing off.
• The form gets this test served either as its main course (POST) or as a side dish (GET). If the script tag shows up in the response like an uninvited guest—ooh boy, red alert! Vulnerable!
• Last but not least, the grand finale. We create an instance, call our brainy methods, and let ‘er rip. Remember, you gotta swap in the actual URL; we’re not really going after example.com.

And there you have it. Like a detective novel but the tech edition. Let’s hope the bad guys don’t get a whiff of this, huh? Thanks for tagging along on this code caper—I’ll catch you on the flippity flip! 🕵️‍♂️💻✨
