Mitigation Strategies Analysis for joomla/joomla-cms

Mitigation Strategy: Rigorous Extension Vetting and Minimization

Mitigation Strategy: Rigorous Extension Vetting and Minimization

Description:

  1. Establish a Policy: Create a written policy for extension selection within the development team. Mandate checking the JED, researching the developer, and limiting extensions to only those absolutely necessary.
  2. JED Review: Before installation, always check the Joomla Extensions Directory (JED) for the extension. Examine user reviews, ratings, and the last updated date. Prioritize extensions with positive feedback and recent updates.
  3. Developer Research: Investigate the extension developer. Look for a website, contact information, and evidence of a commitment to security (security advisories, responsive communication).
  4. Code Review (Optional but Recommended): If feasible, and especially for less-known extensions, download the extension package and examine the code. Look for:
    • Direct SQL queries without proper escaping (using $db->quote() or prepared statements within the Joomla framework).
    • Lack of input validation (using Joomla's JInput class).
    • Use of deprecated Joomla functions.
    • Hardcoded credentials.
    • eval() usage (generally avoid).
  5. Needs Assessment: Before installing any extension, clearly define the specific functionality required. Avoid installing extensions with excessive features.
  6. Regular Review: At least quarterly, review all installed extensions within the Joomla backend. Remove any that are no longer used or have become unmaintained.
  7. Documentation: Document the purpose and vetting process for each installed extension (this can be done within a project management system or a dedicated document).

Threats Mitigated:

  • SQL Injection (Critical):
  • Cross-Site Scripting (XSS) (High):
  • Remote Code Execution (RCE) (Critical):
  • File Inclusion (Local/Remote) (High/Critical):
  • Authentication Bypass (High):
  • Information Disclosure (Medium):

Impact:

  • All Threats: Significantly reduces risk by minimizing the chance of installing a vulnerable extension.

Currently Implemented: Example: Partially implemented. We check the JED and prefer known developers, but we don't have a formal written policy or consistently perform code reviews.

Missing Implementation: Example: Formal written policy, consistent code reviews, regular review of installed extensions, comprehensive documentation.

Mitigation Strategy: Automated and Immediate Extension Updates (via Joomla's Update System)

Mitigation Strategy: Automated and Immediate Extension Updates (via Joomla's Update System)

Description:

  1. Enable Joomla Update Notifications: Ensure Joomla's built-in update notifications are enabled (System -> Global Configuration -> System -> Notifications).
  2. Monitor Notifications (Joomla Backend): Regularly check the Joomla backend's control panel for update notifications.
  3. Immediate Updates (with Testing): As soon as an update is available, test it on a staging environment first. If the update passes testing, apply it to the production site immediately via the Joomla Extensions -> Update interface.
  4. Automated Update System (Joomla Extensions): Consider using a Joomla extension that automates the update process within Joomla. These can:
    • Automatically check for updates.
    • Create backups before applying updates (using Joomla's backup features or an extension like Akeeba Backup).
    • Apply updates automatically (after testing).
    • Roll back updates if problems occur.

Threats Mitigated: (Same as "Vetting and Limiting Extensions")

Impact:

  • All Threats: Dramatically reduces risk by patching known vulnerabilities.

Currently Implemented: Example: Partially implemented. We receive update notifications and update extensions, but not always immediately. We don't have a dedicated staging environment for all updates.

Missing Implementation: Example: Consistent use of a staging environment, immediate patching, exploration of an automated update extension.

Mitigation Strategy: Automated and Immediate Joomla Core Updates (via Joomla's Update System)

Mitigation Strategy: Automated and Immediate Joomla Core Updates (via Joomla's Update System)

Description: (Nearly identical to extension updates, but using Joomla's core update feature)

  1. Enable Joomla Update Notifications: Ensure Joomla's update notifications are enabled.
  2. Monitor Notifications (Joomla Backend): Regularly check the Joomla backend.
  3. Immediate Updates (with Testing): Test on staging, then apply immediately to production via the Joomla Update component.
  4. Automated Update System (Joomla Extensions): Consider an extension for automating core updates (with staging and backups).

Threats Mitigated: (Similar to extensions, but specific to the Joomla core)

Impact:

  • All Threats: Dramatically reduces risk.

Currently Implemented: Example: Partially implemented.

Missing Implementation: Example: Consistent staging, immediate patching, automated update extension.

Mitigation Strategy: Enable and Customize Joomla's .htaccess

Mitigation Strategy: Enable and Customize Joomla's .htaccess

Description:

  1. Rename htaccess.txt: Locate htaccess.txt in the Joomla root. Back it up. Rename the original to .htaccess.
  2. Review Default Rules: Open .htaccess and review the default security rules provided by Joomla.
  3. Customize (Optional but Recommended): Add custom rules relevant to Joomla. Examples:
    • Protect Sensitive Joomla Files: 
      <Files configuration.php>
    order allow,deny
    deny from all
</Files>
    • Prevent Directory Listing: 
      Options -Indexes
  4. Test Thoroughly: After any .htaccess changes, test your Joomla site thoroughly.

Threats Mitigated:

  • Directory Listing (Medium):
  • Direct Access to Sensitive Files (High):
  • Some XSS and Injection Attacks (Low/Medium):

Impact:

  • Directory Listing: Eliminates risk.
  • Direct Access: Significantly reduces risk.
  • XSS/Injection: Minor additional protection.

Currently Implemented: Example: Partially implemented.

Missing Implementation: Example: Review and customization of .htaccess with Joomla-specific rules.

Mitigation Strategy: Restrictive configuration.php Permissions (via server, but for a Joomla file)

Mitigation Strategy: Restrictive configuration.php Permissions (via server, but for a Joomla file)

Description:

  1. Locate configuration.php: In the Joomla root directory.
  2. Check Current Permissions: Use an FTP client or hosting control panel.
  3. Set Permissions: Change to the most restrictive setting that allows Joomla to function (usually 644, or 444 if possible). Test after changing.

Threats Mitigated:

  • Information Disclosure (Critical):

Impact:

  • Information Disclosure: Significantly reduces risk.

Currently Implemented: Example: Implemented.

Missing Implementation: Example: None (potentially test 444).
