SUBJECT: Unsupported Version of Apache HTTP Server Detection

TECH STACK: Apache HTTP Server versions 2.1.x to 2.2.x

CRITICALITY: CRITICAL

OVERVIEW:

The remote host is running an unsupported version of Apache HTTP Server, specifically versions between 2.1.x and 2.2.x. These versions are no longer maintained by the vendor, meaning they do not receive security updates or patches. This lack of support leaves servers vulnerable to security risks, including potential exploits and vulnerabilities that remain unpatched.

THREAT INTELLIGENCE:

Unsupported software poses a significant security risk as it is no longer receiving updates to address newly discovered vulnerabilities. Running an outdated version of Apache HTTP Server can expose your system to various attacks, including but not limited to remote code execution, data breaches, and denial of service attacks.

SOLUTION:

Steps to Mitigate:

  1. Identify Current Version:

    • Verify the current version of Apache HTTP Server running on your system. You can check this by running the following command in the terminal:
      sh
       
      httpd -v

  2. Backup Configurations and Data:

    • Before upgrading, ensure you back up your current Apache configurations and data to prevent data loss.

  3. Upgrade to a Supported Version:

    • Upgrade to the latest version of Apache HTTP Server. At the time of writing, the latest version is 2.4.x.
    • Follow the official Apache HTTP Server documentation for detailed instructions on upgrading from older versions.

  4. Secure Configuration:

    • After upgrading, review and update your server configurations to follow best security practices. Refer to the Apache Security Tips.

  5. Test the Upgrade:

    • After the upgrade, thoroughly test your web server to ensure all services are running correctly and there are no compatibility issues with your web applications.

  6. Regular Updates and Monitoring:

    • Regularly update your Apache HTTP Server to the latest version to ensure you receive the latest security patches.
    • Implement continuous monitoring using tools like Nessus to detect any potential vulnerabilities.
