  Refactor: Remove @csrf_exempt decorator and update response.set_cookie parameters

  The @csrf_exempt decorator has been removed from the auth_failure_lab3 function to enforce CSRF protection. The response.set_cookie calls have been updated to set the secure, httponly, and samesite parameters to enhance security.
  Fix: Set secure, HttpOnly, and SameSite attributes for cookies

  Set secure=True, httponly=True, and samesite='Lax' in response.set_cookie(...) to enhance security and prevent common web vulnerabilities like XSS and CSRF.
  Fix: Secure cookie handling in crypto_failure_lab3 view

  Added 'secure=True', 'httponly=True', and 'samesite='Lax'' to enhance cookie security in the 'crypto_failure_lab3' view. These settings ensure that the cookie is only transmitted over HTTPS, not accessible to client-side JavaScript, and only sent for requests originating from the same site, respectively. This mitigates the risk of common web vulnerabilities such as cross-site scripting (XSS) and cookie theft.
  Fix: Secure password hashing

  Replaced the insecure MD5 hashing algorithm with scrypt for password hashing to enhance security.
  Fix: Prevent SSTI in user-generated blogs

  Used the Django template rendering engine to safely render user-generated blog content, preventing server-side template injection (SSTI) vulnerabilities.
  Fix: Mitigate SSRF vulnerability in ssrf_lab2 view

  Introduced input validation to prevent SSRF attacks through the 'url' parameter in the ssrf_lab2 view. The validation checks if the URL scheme is either 'http' or 'https' and if the hostname is 'www.example.com'. The response from the requested URL is no longer directly rendered, mitigating potential information disclosure.
  Fix: Mitigate path traversal vulnerability

  Used os.path.abspath(filename) to get the absolute path of the requested file. This prevents attackers from using ".." or similar path traversal techniques to access files outside the intended directory.
  Fix: Prevent SQL injection vulnerability

  The original code was vulnerable to SQL injection attacks due to the use of string concatenation to build SQL queries. This commit addresses the vulnerability by using parameterized queries, effectively preventing attackers from manipulating the SQL query. Additionally, the unnecessary csrf_exempt decorator has been removed to enforce CSRF protection.
  Fix: Remove csrf_exempt decorator from injection view

  Removed the csrf_exempt decorator from the injection view to enforce CSRF protection. This prevents potential CSRF attacks by requiring a valid CSRF token for requests to this view.
  Removed csrf_exempt decorator

  Removed the csrf_exempt decorator from the a1_broken_access_lab_2 function. This change enforces CSRF protection for this view.
  Removed csrf_exempt decorator

  The csrf_exempt decorator has been removed from the a1_broken_access_lab_1 function. This change ensures that the route is protected by CSRF tokens, preventing potential CSRF attacks. However, it requires that CSRF middleware is properly configured and CSRF tokens are included in the relevant forms or requests.
  Fix: Remove @csrf_exempt decorator from a1_broken_access view

  Removed the @csrf_exempt decorator from the a1_broken_access view function. This ensures that the CSRF middleware provided by Django is active for this route, protecting it from Cross-Site Request Forgery attacks.
  Fix CSRF vulnerability in a9_lab2 view

  Removed the @csrf_exempt decorator from the a9_lab2 view and added CSRF token validation to ensure that requests are originating from trusted sources, protecting against CSRF attacks.
  Fix YAML deserialization vulnerability

  Replaced yaml.load with yaml.safe_load to prevent arbitrary code execution during YAML deserialization.
  Removed csrf_exempt decorator from Otp view

  The csrf_exempt decorator has been removed from the Otp view. This change enforces Cross-Site Request Forgery (CSRF) protection for this route.
  Fix: Secure command execution in cmd_lab view

  Removed the @csrf_exempt decorator from the cmd_lab view to enforce CSRF protection.
  Refactored the command execution logic to prevent command injection vulnerabilities. Instead of dynamically constructing the command string based on user input, the code now uses a predefined dictionary to map operating system choices to safe and validated commands.
  Disabled the use of shell=True in the subprocess.Popen call to prevent potential shell injection attacks.
  Fix CSRF vulnerability

  Removed the @csrf_exempt decorator from the ba_lab function to enforce CSRF protection. This prevents attackers from manipulating the user's account.
  Removed @csrf_exempt decorator and added CSRF token to template

  The @csrf_exempt decorator has been removed from the ba function to enforce CSRF protection. The CSRF token has been added to the ba.html template to prevent CSRF attacks.
  Fix: Use JsonResponse to prevent potential XSS vulnerability

  Replaced HttpResponse with JsonResponse to leverage Django's built-in XSS protection. JsonResponse automatically escapes data for safe rendering in HTML.
  Fix: Securely handle cookies and use Django's template rendering

  The code has been modified to enhance security and prevent potential XSS vulnerabilities. It now leverages Django's template rendering for safer HTML output. Cookies are now handled more securely by setting appropriate flags, ensuring they are not accessible by JavaScript and are only sent over HTTPS connections.
  Fix: Securely handle cookies and use template rendering

  The code now uses Django's template rendering to prevent potential XSS vulnerabilities. The cookie handling has been updated to set secure=True, httponly=True, and samesite='Lax' by default, enhancing security. The 'try-except' block was redundant, since render() already handles any exceptions.
  Fix: Remove @csrf_exempt decorator and add CSRF token

  Removed the @csrf_exempt decorator from the xxe_see view function. This ensures that the CSRF token is required for requests to this route, mitigating the risk of CSRF attacks. The CSRF token is added to the context of the template.
  Fix: Secure cookie handling and replace 'pickle' with safer serialization

  The code has been modified to enhance security in two key ways:

  1. Secure Cookie Handling: The set_cookie method now includes secure=True, httponly=True, and samesite='Lax' to enhance cookie security. This helps prevent common attacks like cross-site scripting (XSS) and cookie theft.

  2. Safer Serialization: The use of pickle for deserialization, which is vulnerable to remote code execution, has been replaced with a safer approach. The code now uses json for serialization and deserialization, mitigating the security risk associated with pickle.

  Remove @csrf_exempt decorator

  Removed the @csrf_exempt decorator from the mitre_lab_17_api function. This change ensures that the route is protected by CSRF tokens, preventing potential CSRF attacks.
  Fix vulnerability: Use shell=False in subprocess.Popen

  Replaced 'shell=True' with 'shell=False' in the subprocess.Popen call to prevent potential command injection vulnerabilities. The command is now passed as a list, ensuring that it's treated as a single entity and preventing the shell from interpreting special characters or expanding variables.
  Fix CSRF and code injection vulnerabilities

  Removed the use of @csrf_exempt decorator and replaced it with Django's built-in CSRF protection. This change ensures that a CSRF token is required for all POST requests, preventing cross-site request forgery attacks. Refactored the code to remove the use of eval() which was used to evaluate mathematical expressions. Implemented a safer approach using ast.literal_eval() from Python's abstract syntax tree module. This change mitigates the risk of code injection vulnerabilities by ensuring that only valid Python expressions are evaluated.
  Fix: Remove @csrf_exempt decorator and add CSRF token to form

  Removed the @csrf_exempt decorator from the csrf_transfer_monei view. This ensures that Django's CSRF protection mechanism is enforced for this view, mitigating the risk of CSRF attacks. The system now requires a valid CSRF token to be submitted with the request, which helps prevent unauthorized actions on behalf of the user.
  Fix: Secure password hashing and JWT practices

  The code was updated to use scrypt for password hashing instead of the insecure MD5 algorithm. Additionally, the hardcoded JWT secret has been removed, and instructions for securely storing and accessing it via environment variables have been added. Lastly, the set_cookie method in the response now includes security enhancements: secure=True, httponly=True, and samesite='Lax' to enhance the security of the authentication cookie.

  Fix: Prevent potential XSS vulnerability in script tag

  The variable https://github.com/patched-codes/pygoat/pull/10/files#diff-8037efed3ec414dbca611108572587118f7962ed143ae460842e401178a80470 was being directly rendered inside a script tag. This could lead to XSS even though it's HTML escaped. The fix moves the data rendering outside the script tag into a hidden input field. The JavaScript code then fetches this data from the input field using its ID.
  Add CSRF token to form

  Added {% csrf_token %} to the form to prevent CSRF attacks.

  Fix: Mitigate potential XSS vulnerability in template

  Addressed a potential XSS vulnerability where a template variable was directly used within a <script> tag. The fix replaces the direct use of https://github.com/patched-codes/pygoat/pull/10/files#diff-5694d08a2e53ffcae0c3103e5ad6f6076abd960eb1f8a56577040bc1028f702b with document.getElementById('code-container').textContent to retrieve the content securely from a dedicated HTML element. Additionally, the code variable is now safely embedded in a <span> tag with the ID 'code-container' to facilitate this retrieval. This approach ensures that the content is treated as data, mitigating the risk of script injection.
