This solution refers to which of the apps?

A6 - Cimentech

What did you do to mitigate the vulnerability?

I applied several security enhancements to mitigate the vulnerabilities found in the Cimentech application:

1. Drupal Version Upgrade:

   • Upgraded the Drupal version to the latest stable release to address known security vulnerabilities, ensuring the application is using a more secure and supported version.

2. Improved .htaccess Security Configuration:

   • Access Restrictions: Restricted access to critical files and directories (e.g., .engine, .inc, .module, .sql) to prevent unauthorized users from accessing sensitive information.
   • Directory Listings: Disabled directory listings to hide file structures from potential attackers.
   • PHP Execution Prevention: Blocked PHP execution in the wp-content/uploads directory to mitigate remote code execution attacks from file uploads.
   • Security Headers: Implemented security headers, such as:
     • X-Content-Type-Options to prevent MIME-type sniffing.
     • X-XSS-Protection to enable Cross-Site Scripting (XSS) protection.
     • X-Frame-Options to prevent Clickjacking attacks.
     • Content-Security-Policy to restrict sources for scripts, styles, and other content types.
   • Directory Restrictions: Prevented PHP script execution in wp-includes and blocked access to sensitive WordPress files, such as xmlrpc.php.

3. Docker Configuration Adjustments:

   • Updated the Docker configuration to ensure compatibility with the latest Drupal version and the modified .htaccess rules. This step ensures a smoother deployment and operation in the containerized environment.

Did you test your changes? What commands did you run?

• Tested the updated Drupal version to ensure all core functionalities are operational and no compatibility issues exist with the upgraded version.
• Manually validated .htaccess rules using an Apache server to confirm that access restrictions and security headers were applied as expected.
• Verified the build and deployment process of the Docker container to ensure the updated configurations were correctly applied.

These changes help mitigate risks associated with outdated components, unauthorized file access, and other security misconfigurations, significantly improving the overall security posture of the application.
