  Fixed authentication decorator to set secure cookie

  Added secure=True to set_cookie to ensure secure transmission of cookie over HTTPS
  Secure handling of cookies

  The code sets secure=True, httponly=True, and samesite='Lax' when setting cookies to ensure secure handling of cookies.
  Fixed SSTI vulnerability by using secure templating and escaping techniques

  This commit fixes a Server-Side Template Injection (SSTI) vulnerability by using secure templating and escaping techniques. The vulnerability was found in the ssti_lab view function, where user-controlled input was being used to render a template. This commit replaces the direct use of Jinja2 with Flask's render_template function, which properly escapes user input. Additionally, the filter_blog function was removed as it was not necessary.
  Fixed SSRF vulnerability by validating URL schemes and hosts against an allowlist.

  Added checks for allowed schemes ("http", "https") and hosts ("example.com", "localhost") for the URL to be proxied. Also, added proper error handling to prevent SSRF attacks.
  Removed @csrf_exempt decorator to prevent potential CSRF attacks.

  The @csrf_exempt decorator was removed from the injection_sql_lab function to prevent potential CSRF attacks. This was done to ensure that only authenticated users can access this route.
  Fixed vulnerability by removing @csrf_exempt from injection route.

  Removed @csrf_exempt decorator from injection route to ensure CSRF token validation.
  Fixed broken access control vulnerability by removing @csrf_exempt decorator and ensuring secure access control for sensitive routes.

  The original code has been modified to remove the @csrf_exempt decorator from the 'a1_broken_access' function. This decorator was incorrectly used to exempt the route from CSRF validation, which could have led to potential security risks.
  Fixed command injection vulnerability in cmd_lab function.

  Replaced subprocess command with a whitelist of allowed commands to prevent command injection attacks.
  Fixed XSS vulnerability by rendering template instead of HttpResponse

  Replaced HttpResponse with render function to render template instead of directly rendering HTML to HttpResponse.
  Fixed XSS vulnerability by using Django's template engine to safely render HTML.

  The original code directly rendered HTML to the end user via 'HttpResponse', bypassing Django's built-in cross-site scripting (XSS) defenses. This has been fixed by using Django's template engine to safely render HTML.
  Avoid using pickle for serialization

  Replaced pickle serialization with JSON serialization to prevent potential code execution vulnerabilities.
  Fixed SQL injection vulnerability by using parameterized queries.

  The vulnerable code used raw SQL queries to filter users and validate passwords. This has been replaced with Django ORM queries using parameterized queries to prevent SQL injection attacks.

  Fix CSRF vulnerability by adding csrf_token to form

  This commit adds the csrf_token to the form to prevent CSRF attacks.

• File changed: introduction/apis.py
  Fixed potential file write vulnerability by properly escaping user-controlled input.

  The original code writes user-controlled input directly into log files without proper sanitization. This vulnerability could allow an attacker to manipulate sensitive files. The fix replaces user-controlled input with sanitized values to prevent potential attacks.

• File changed: introduction/templates/Lab/CMD/cmd_lab2.html
  Fix CSRF vulnerability by adding https://github.com/patched-codes/pygoat/pull/7/files#diff-f19ab9cb11c837166f75090f18cb7b030d9811f74cc50c257f040dbc84053916 to the form.

  The https://github.com/patched-codes/pygoat/pull/7/files#diff-f19ab9cb11c837166f75090f18cb7b030d9811f74cc50c257f040dbc84053916 tag was added to the form to include it in the generated HTML. This ensures that the form includes a CSRF token to prevent CSRF attacks.

• File changed: introduction/templates/Lab/XSS/xss_lab_3.html
  Fixed XSS vulnerability by removing template variable usage directly in script tag.

  The original code used a template variable https://github.com/patched-codes/pygoat/pull/7/files#diff-5694d08a2e53ffcae0c3103e5ad6f6076abd960eb1f8a56577040bc1028f702b directly in a script tag https://github.com/patched-codes/pygoat/pull/7/files#diff-ed79378f59fd2345cb3fd9032918be8a9648e175b74f3faa47bf4176ec2dc4f2. This could potentially allow cross-site scripting (XSS) attacks. To mitigate this, the https://github.com/patched-codes/pygoat/pull/7/files#diff-5694d08a2e53ffcae0c3103e5ad6f6076abd960eb1f8a56577040bc1028f702b variable has been removed from the script tag.

• File changed: introduction/templates/Lab_2021/A1_BrokenAccessControl/broken_access_lab_1.html
  Fix csrf vulnerability in django template

  The 'form' tag in the template now includes the '{% csrf_token %}' directive to ensure that the form includes a CSRF token, mitigating against CSRF attacks.
